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

if it is the radius you can find area or circumference

you divide the area by pi. then, find the square root of the number you have. now you have the radius. find the circumference by multiplying by the diameter or by multiplying by two times the radius.

Area of a circle = 3.14 * r2 Thus, radius, r = root of ( Area of a circle / 3.14 ) --------- equation 1 Circumference of circle = 2 * 3.14 * r Therefore, from (equation 1), Circumference = 2 * 3.14 * root of ( Area of a circle / 3.14 ). In a nutshell, first find the radius and then the circumference.

Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference

Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared

To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.

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

The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.

Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference

Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
