Because the circumference is equal to the diameter multiplied by pi or the radius multiplied by 2*pi.

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

Circle's circumference = 2*pi*radius or diameter*pi

to find the circumference of a circle you do 2 times3.14timesthe radius

The circumference of a circle is equal to the radius, multiplied by 2 x pi. Thus, in this case, you can divide the circumference by 2 x pi, to get the radius.

Formula for finding the circumference of a circle: 2 multiplied by pi multiplied by radius

An arc is part of a circumference of a circle. The circumference itself is an arc length. The circumference of a circle is found by using the formula circumference (C) is equal to 2 multiplied by pi and the radius, or 2 x pi x r, where r is the radius and pi is 3.14.

Assuming you mean the Circumference of a Circle: C = 2 x pi x Radius or C = pi x Diameter
