Answer:
The area of a circle is pi times the radius squared (Area = pi radius²).
Step-by-step explanation:
The circumference of a circle is the linear distance of a circle's edge. It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.
The following equation describes the relation between the circumference and the radius R of a circle:
C = 2πR
Where π is a constant approximately equal to 3.14159265..
How to find the circumference of a circle
Determine the radius of a circle. Let's assume it's equal to 14 cm.
Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm.
You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm².
Finally, you can find the diameter - it is simply double the radius: D = 2 * R = 2 * 14 = 28 cm.
Use our circumference calculator to find the radius when you only have the circumference or area of a circle.
Answer:
Use this formula: A = π r²
Step-by-step explanation:
A = π r²
What does A = π r² mean? :
(Area = Pi x Radius²)
π = Pi (3.14)
² = squared

What is the area of a triangle with a base of 7 mm and a height of 10 mm
Answer:
A≈3.5×10-5m²
Step-by-step explanation:
The requried area of the given triangle is 35-millimeter square.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
What is an area of a triangle?The area of the triangle is given as half the product of the height and base of the given triangle.
Area of the triangle = 1/ 2 base × height
here,
in the given question, height = 10 mm and base = 7 mm
Area of the triangle = 1/ 2 10 × 7
Area of the triangle = 35 mm²
Thus, the requried area of the given triangle is 35-millimeter square.

Answer:
Step-by-step explanation:
Empirical Rule establishes that 68% of the population will fall in the interval μ₀ ± σ Then
348*0,68 = 237
237 students will be between ( 100-15 ; 100+15) That is

y = -x2 + x.
9514 1404 393
Answer:
none
Step-by-step explanation:
The equations describe curves that do not intersect. There are no real solutions.
_____
Additional comment
The system is consistent, not dependent, and of degree 2, so there will be two solutions. There are no real solutions, so the two solutions are complex: (-2i, 4-2i) and (2i, 4+2i).
Write each as a decimal. Round to the hundredths place.

who is right and wrong and why?
Answer:
BMX Ben is correct and Pizza Pete is wrong
Step-by-step explanation:
For Both equations, we must isolate the x, or move everything to one side. So you'd have to add 25 because you have a negative 25 and a negative number plus a positive version of itself equals 0
x-25=7
+25=25
__________
x=32
The second one is incorrect because you are subtracting negative 25 from a 25, which is -50

A photographer has enough liquid toner for sixty 4 in. by 8 in. prints. How many 11 in. by 14 in. prints will this amount cover?
(The toner covers the area of the print: Area=Length×Width)
The toner will cover ___ ( 13,11, 12, 48) prints of size 11 in. by 14 in.
Answer:
About 12 prints in 11×14
Step-by-step explanation:
The area of the 4×8 print is 32 in².
60 × 32= 1960
Divide by the area of an 11×14, 154 in²
1960/154 ≈ 12.47
There is enough for a little more than 12, but not enough for 13 prints.

What is 0.36¯¯¯¯ expressed as a fraction in simplest form
Answer:
I think this is probably late, but the answer is 4/11.
Step-by-step explanation:
0.36363636363 is the first repeating fraction and 36.36363636 is the second repeating fraction, because you multiply it by 100.
When 0.3636363636363 is multiplied by 100, the decimal moves from in front of the number 36 and moves behind it. So the answer is now 36.36363636
You're suppose to subtract those two minus each other, the denominator
the fraction is technically 36/99, but simplified version is 4/11. So the answer is indeed 4/11.
Thanks for your time!
Step-by-step explanation:
Answer:
:0.36 repeating can be expressed as 36/99

Consider matrices A, B, and C.
Which matrix represents (A-B)-C?
Answer:
B.) I cant insert a 2x2 matric but the [5 7
7 4] matrix is correct
Step-by-step explanation:
I got a 5/5 on the test so I know that B is the correct answer
The matrix which represents (A-B)-C will be the matrix in option (B).
What is the matrix?matrix, a collection of numbers lined up in rows and columns to produce a rectangular array. The elements of the matrix, also known as the entry, are the numerals.
In another word, a matrix is a set of variables that are arranged in such a good way that we can create algebraic equation from that.
In computer graphics, where they have been used to describe picture transformations and other alterations, matrices have vital applications as well in many sectors.
Given that the matrix
A - B = [first raw 3 ,1 in second raw 2 ,0]
Now (A - B) - C = [ first raw 5 ,7 in second raw 7 , 4]
Hence, the correct option is (B).
