on solving the provided question we can say that length of the major arc angle is [tex](29/6)\pi or 4.83\pi[/tex].
what are angles?In Euclidean geometry, an angle is a shape that is made up of two rays, known as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays may combine to form an angle in the plane where they are positioned. When two planes collide, an angle is also created. These are referred to as dihedral angles. An angle in plane geometry is the possible configuration of two rays or lines that share a termination. The origin of the English term "angle" is the Latin word "angulus," which meaning "horn." The vertex is the point where the two rays, also known as the sides of the angle, converge.

angle subtended at the center = 70 degrees.
Angle = 360 - 70 = 290

A swimming pool is 50 m in length, 30 m in breadth, and 2.5 m in depth. find the cost of cementing its floor and walls at the rate of rupees 27 per square metre?
Answer:
51,300 rupees
Step-by-step explanation:
Surface area of the 2 short walls = 2 x 30 x 2.5 = 150
Surface area of the 2 long walls = 2 x 50 x 2.5 = 250
Surface area of the floor = 50 x 30 = 1500
Total surface area = 150 + 250 + 1500 = 1900 m²
27 rupees/m² x 1900 m² = 51300 rupees

How to find a vector equation and parametric equations for the line segment that joins p to q?
The vector and parametric equations are r(t) = [t/2, (4t/3 - 1), (1 - 3t/4)] and x = t/2, y = -1 + 4t/3, z = 1 - 3t/4.
We have P(0, -1, 1), Q(1/2, 1/3, 1/4)
We have to find a vector equation and parametric equations for the line segment that joins P to Q.
Vector equation of a line segment joining the points with position vectors r0 and r1 is given by
r =(1 - t)r0 + tr1
Where, t ∈ [0, 1]
Here, r0 = (0, -1, 1) and r1 = (1/2, 1/3, 1/4)
So, r(t) = (1 - t)(0, -1, 1) + t(1/2, 1/3, 1/4)
r(t) = [((1 - t)(0) -1(1 - t) + 1(1 - t)] + [t/2, t/3, t/4]
r(t) = [0, (t - 1), (1 - t)] + [t/2, t/3, t/4]
On simplification,
r(t) = [(t/2 + 0), (t + t/3 - 1), (1 - t + t/4)]
r(t) = [t/2, (4t/3 - 1), (1 - 3t/4)]
Where, t ∈ [0,1]
The parametric equations for the line segment are
x = t/2, y = -1 + 4t/3, z = 1 - 3t/4
Where, t ∈ [0, 1]
Therefore, the vector and parametric equations are r(t) = [t/2, (4t/3 - 1), (1 - 3t/4)] and x = t/2, y = -1 + 4t/3, z = 1 - 3t/4.

Warren earns $21.75 per hour and worked 36.5 hours last week and 32 hours the
week before. What is Warren's gross pay for the two weeks? Show your work.
Answer:
$1,489.88 (nearest cent)
Step-by-step explanation:
To calculate gross pay, multiply the number of hours worked by the pay per hour.
Warren worked 36.5 hours one week and 32 hours the week before.
Therefore, the total number of hours Warren worked was:
36.5 + 32 = 68.5 hoursMultiply the total number of hours worked by Warren's rate of pay of $21.75 per hour:
68.5 × 21.75 = 1489.875Therefore, Warren's gross pay for the two weeks was $1,489.88 (nearest cent).
Answer:
$1489.875
Step-by-step explanation:
Warren's gross pay for 36.5 hours last week can be calculated as follows:
Gross pay for 36.5 hours = $21.75/hour * 36.5 hours = $793.875
Similarly, Warren's gross pay for 32 hours the week before can be calculated as follows:
Gross pay for 32 hours = $21.75/hour * 32 hours = $696
Adding the gross pay for the two weeks, we get:
Gross pay for 2 weeks = $793.875 + $696 = $1489.875
how to convert m/s to rad/s?
By using the formula that connects the linear velocity to the angular velocity, we may convert metres per second (m/s) to radians per second (rad/s).
Using the formula that connects the linear velocity to the angular velocity, we may convert metres per second (m/s) to radians per second (rad/s).
The equation reads: Radius divided by linear velocity gives you the angular velocity (). (r) where R is in metres, V is in m/s, and is in rad/s.
Direct conversion from m/s to rad/s is not possible if the radius is omitted. The aforementioned formula can be used to determine the missing value and then convert m/s to rad/s if you know the radius or the angular velocity. You can use the formula to determine the angular velocity in rad/s, for instance, if you know the linear velocity v in m/s and the radius r in metres.

A farmer wants to build a new grain silo. The shape of the silo is to be a cylinder with a hemisphere on top, where the radius of the hemisphere is to be the same length as the radius of the base of the cylinder, which is 15 feet. The height of the cylinder is 30 feet.
The farmer would like to paint the outside of the silo blue when he is finished. How much area will he have to cover to paint the outside of the silo? (Use 3.14 for pi.)
Answer:
Step-by-step explanation:
To find the surface area of the silo, we need to calculate the areas of the cylinder and hemisphere separately, and then add them together.
The formula for the surface area of a cylinder is:
A_cylinder = 2πrh + 2πr^2
where r is the radius of the base of the cylinder, and h is the height of the cylinder.
In this case, r = 15 feet and h = 30 feet, so we have:
A_cylinder = 2π(15)(30) + 2π(15)^2
A_cylinder = 900π + 450π
A_cylinder = 1350π
The formula for the surface area of a hemisphere is:
A_hemisphere = 2πr^2
where r is the radius of the hemisphere.
In this case, the radius of the hemisphere is also 15 feet, so we have:
A_hemisphere = 2π(15)^2
A_hemisphere = 450π
To find the total surface area of the silo, we add the surface areas of the cylinder and hemisphere:
A_total = A_cylinder + A_hemisphere
A_total = 1350π + 450π
A_total = 1800π
Using 3.14 for π, we can approximate the total surface area as:
A_total ≈ 5652 square feet
Therefore, the farmer will need to cover approximately 5652 square feet of surface area to paint the outside of the silo.

What is a reflex angle?A reflex angle is an angle that is more than 180 degrees and less than 360 degrees. For example, 270 degrees is a reflex angle. In geometry, there are different types of angles such as acute, obtuse and right angles, which are under 180 degrees.
Given that angle B is the reflex angle of angle A, angle is measuring 65°
We need to find the measure of reflex Angle B
We know that,
To find the reflex angle of a given angle, we need to subtract the given measure from 360 degrees.

What is surface area ?Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. It is a measure of how much area the surfaces of an object take up in two dimensions. The surface area of a solid can be found by adding up the areas of its faces.
To calculate the amount of wrapping paper needed, we need to find the total surface area of the gift box. The surface area of a right rectangular prism is given by the formula:
surface area = 2(lw + wh + lh)
where l, w, and h are the length, width, and height of the prism, respectively.
In this case, the dimensions of the gift box are 9 meters, 9 meters, and 15 meters, so:
surface area = 2(9 x 9 + 9 x 15 + 15 x 9)

Frequency Distribution Table:The frequency distribution table is made by building the class intervals of the raw data set, specifically when too many values are occurring many times; we group similar values in the same category, according to a pre-determined range of values. It is a two-column table in which the first column consists of class intervals and the second consists of the frequency corresponding to each interval.
The frequency distribution is made when the raw data is large and when the same number is repeated many times, that is where the concept of frequency comes into play.
Since, the frequency is the count of specific numbers in a data set, the sum of all frequencies corresponding to every class interval has to be the total number of values in the data set.
