Circumference = diameter * pi
20 = diameter * pi
20/pi = diameter
(20/pi)/2 = radius
10/pi = radius
Area = (radius)2 * pi
Area = (10/pi)2 * pi
Area = 100/pi2 * pi
Area = 100/pi
Area ≈ 31.83 square units

How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
What is the formula for finding circumference and area of a circle?
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
What is the relationship between the circumference of a circle and the area of a circle?
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
What is the surface area of a sphere whose great circle has a circumference of 40pi?
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)
