If you mean a circle, the circumference is equal to the diameter multiplied by pi.

The circumference of a circle is (diameter) multiplied by (pi).

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

The circumference of a circle is given by pi multiplied by its diameter. pi is just a number, equalling approximately 3.141592654. So, we multiply pi by 11.74 to get a circumference of about 36.88.

The circumference is Pi multiplied by the diameter. In this case, the circumference is 18Pi. We can only approximate this since Pi is an irrational number. The circumference is about 56.55 inches.
