What is the radius of a circle (rounded to the nearest tenth) that has an area of 48?

Answers

Answer:

3.9

Step-by-step explanation:

Use the formula A = πr^2 (area of a circle = Pi times radius squared)

Plug in what we know:

48 = πr^2 (first, divide 48 by Pi = that would equal 15.27887 continued, round it to the nearest tenth and you would get 15.3)

15.3 = r^2 (now, we find the square root of 15.3, 3.9115 continued, round it to the nearest tenth, and it will be 3.9)

3.9 = radius

The radius of the circle (rounded to the nearest tenth) is 3.1.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.

And the general formula of the circle,

(x – h)²+ (y - k)² = r²,

where (h, k) is the center and r is the radius of the circle.

The formula for the area of a circle is A = πr², where A is the area and r is the radius.

We can use this formula to solve for the radius of the circle with an area of 48:

A = πr²

48 = πr²

Dividing both sides by π gives:

r² = 48/π

Taking the square root of both sides gives:

r = √(48/π)

r ≈ 3.1

Therefore, r ≈ 3.1.

Base on tangent and secant rule for intersection,

The length of WZ is 12.

The angle of the arc XZ is 39 degrees.

What is tangent of a circle

The tangent to a circle is defined as a straight line that touches the circle at a single point.

Therefore,

WX × WY = WZ²

8 × (10 + 8) = WZ²

8 × 18 = WZ²

WZ² = 144

WZ = √144

WZ = 12

74° = 1 / 2(187 - arc XZ)

74 = 93.5 - arcXZ / 2

-19.5 = - arcXZ / 2

-39 = - arcXZ

-arcXZ = 39°

The sum of two numbers is 39. the second number is 6 more than half of the first number. let a represent the firstnumber and let b represent the second number. what are the two numbers? use the table to answer the question.

Answers

Answer:

a = 22b = 17

Step-by-step explanation:

Givens

Let a = the first number

Let b = the second number

Equations

a + b = 39

b = 1/2 * a + 6

Put the second equation into the first one

a + 1/2 * a + 6 = 39 Simplify the left.

(3/2)a + 6 = 39 Subtract 6 from both sides

(3/2)a + 6 - 6 = 39 - 6 Combine

(3/2)a = 33 Multiply both sides by 2

3a = 33*2

3a = 66 Divide both sides by 3

3a/3 = 66/3

a = 22

b = 1/2 a + 6

a = 22

b = 1/2 * 22 + 6

b = 11 + 6

b = 17

Check

22 + 17 = 39

Katrina is going to paint the front door of her house. What is the area of the door? Use 3.14 for pi.

Answers

So for the rectangle part you work out the area which is length x width. So you do 5*4 =20. To work out the semi circle you need to know the area for a circle. The equation is pi*r^2. So you do 3.14*(2)^2. R is the radius in the equation. The radius is half the diameter so you divide 4 by 2 to get that. So the answer to the semicircle is 12.56. Finally you need to add them together. So the answer is 32.56.

the diagram represents the unit rate of making copies on a copy machine. Which table represents the rate of making copies on this copy machine?

Answers

The unit rate is the amount of book copy made in a second

The table that represents the unit rate is table (b)

How to determine the table?

The interpretation of the diagram for making copies is:

Rate = 4 copies per second

This means that:

The table that represents this diagram must have a slope or rate of 4

From the list of options, the table (b) has a slope of 4.

This is calculated as:

Slope = Copies/Time

So, we have:

Slope = 40/10 = 4

Hence, the table that represents the unit rate is table (b)

Lucas and Zoe visit their mother on April 7th. From then on, Lucas visits his mother every
fifth day and Zoe visits every eighth day. On what date will Lucas and Zoe both next visit their
mother at the same time?

Answers

Answer:

Lucas and Zoe will both next visit their mother on 7th of May at the same time.

Step-by-step explanation:

First, find the first multiple that can be divisible by 5 and 8:

40 is divisible by 5 and 8.

Second, find the days in April and subtract 7 from the days:

April=30 days.

30-7= 23 days.

Finally, subtract 23 from 40 and find it in the next month, which is May:

40-23=17

Therefore, they will both next visit their mother on the 7th of May.

Add the y and the numbers together
-3y + -2y = -5y
26 + -16 = 10
-5y = 10
y = -2
Use y=-2 in one of the equations
-3(-2) + 5x = 26
6 + 5x = 26
5x = 20
