Circumference of a circle = 2*pi*radius

find the radius of a circle with circumference of 42.1

2 x 3.142 x radius = circumference. 3.142 is known as pi.

To find the circumference of a circle, you need to multiply the radius by 3.14.

For a circle, circumference = 2 x pi x radius.

By using the equation 2πr that is used to find the circumference, you get 12.56m

A circle with a radius of 8 inches has a circumference of 50.27 inches.

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.

The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.

Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius

The formula; 2 * Pi * Radius = circumference Will calculate the circumference of a circle.
