Divide the area by the value of Pi to get the diameter. Divide the diameter by 2 to get the radius !

Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared

Divide the area by pi and then square root it this will give the radius of the circle.

What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi

Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18

you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi

It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.

The formula for area of a circle is TTr2.This means that we multiply 3.14(the rounded off nunber for pi) by the radius and radius(3.14xradiusxradius).If the diameter is given,divide it by 2 to get the radius.

Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.
