Divide the diameter by 2, this will give you the radius. multiply the radius by the radius, this gives you the radius squared. Multiply the raduis squared by Pi (3.14) to get the circumference.
Formula : Circumfrence = Pi X R squared
so, if the diameter is 10, the radius is 5, the radius squared is 25, 25 X 3.14= circumference

The circumference is pi times the diameter.
Yes because: circumference/diameter = pi and circumference = pi*diameter
Circumference = diameter x pi
The diameter of a circle is the length of a line passing through the center of a circle that connects two points on the circumference. The circumference is the distance around the edge of a circle.
Diameter of a circle = circumference/pi
