How do you find the circumference of a circle?

Circumference = pi times radius squared.

C = pi * r^2

Answer of Ms.Sue is wrong.

The circumference is the distance around a closed curve. Circumference is a special perimeter.

The circumference of a circle is the length around it. The circumference of a circle can be calculated using the formulas:

C=d*pi

Wher d is diameter

OR

C=2*r*pi

Wher r is radius

In google type: Circumference

When you see list of results click on :

Ooops! I goofed again! I guess I'd better screw my head on tighter.

Of course, Bosnian is right.

C = pi * diameter

I gave the formula for the area.
