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:

$\text {circumference of circle }=2 \pi r$

Where "r" is the radius of circle

Substituting the value r = 18 inches in above formula,

$\text {circumference of circle }=2 * \pi * 18=36 \pi$

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