What is area of a circle if circumference equals pi divided by 2?
Area of a circle is: pi times radius squared
How is pi used to determine the area of a circle?
Area of a circle equals pi (3.14) times the radius squared.
If the area of a circle is 25 square units what is the radius of the circle?
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
Is the area of a circle is twice the radius?
Area equals pi times the radius squared.
Does the area of a circle equal pi?
no, the area of a circle equals pi times the radius squared or circumference times diameter over four.
What is area of a circle if circumference equals pi divided by 2?
Area of a circle is: pi times radius squared
How is pi used to determine the area of a circle?
Area of a circle equals pi (3.14) times the radius squared.
How do you fin the area of a circle?
The area of a circle equals pi x r squared or A = pi x r2 A = area of circle pi = approximatley 3.14 r = radius

no, the area of a circle equals pi times the radius squared or circumference times diameter over four.
What is the area of a circle with a circumference of 10 pi?
Using 3.14 as Pi the area of circle is: 0
What is the formula for the surface area of a circle?
The formula for the surface area of a circle is pi times the square of the radius. It is represented as A equals pi times r squared.
What value should you get if you divide the area of any circle by the square of its radius?
You will get pi since area of a circle equals pi* times radius squared....by Mona Martinez
What is the area of a circle if the diameter is 9.75 if pi is 3.14?
The area equals pi times the radius squared. The radius is half the diameter. The area of the circle = (9.75/2)2(3.14) = 74.6240625 or about 74.6 units squared.
Formula of area of a circle?
Area of a circle = pi*radius2 measured in square units
How do you find the radius of a circle if you already know the area?
The area of a circle equals pi times the radius squared (A = pi*radius2) where pi is 3.1416 So the radius is the square root of the area divided by 3.1416
