Find the circumference. leave your answer in terms of pi.

The circumference of circle with radius 18 inches in terms of pi is 36π inches

From the given figure, radius "r" = 18 inches

We have to find circumference of circle

circumference would be the length of the circle if it were opened up and straightened out to a line segment.

The circumference of circle is given as:

Where "r" is the radius of circle

Substituting the value r = 18 inches in above formula,

Thus circumference of circle in terms of pi is 36π inches
