Question

The diameter of a circle is 19 in. Find its circumference in terms of \piπ.

Answer 1

The circumference is 59.6903

Explanation:

In order to find the circumference, use the equation C=2πr

Radius is essentially half of the diameter, so 9.5 is our radius

C=2π(9.5)

C≈59.6903

Answer 2

Circumference = 2pi(radius)

C = 2(pi)(9.5)

C = 19pi

The answer is 19pi.
