Best Answer

C=2*pi*r

A=pi*r^2

so you divide the circumference by 2*pi (~6.28), then square that and multiply by pi (~3.14) and that would get you the area of a circle

i.e. if Circumference = 62.8 inches...you divide by 6.28 and get 10, then you square that (10*10=100), then you multiply by pi...100*3.14= 314 square inches.

If the circumference of a circle is 6.28 then its area is about 3.138 square units

The area of circle with a circumference of 20 is: 31.83 units squared.

The circumference of a circle with an area of 3 acres is: 1,281 feet.

what is the area and circumference of a circle with a diameter of 55 centimeters

The circumference of a circle is a line. Because it is a line it has no area, only length. So the area of the circumference cannot exist!
