The radius of a circle is 3 in. Find its circumference in terms of piπ.

Answer 1

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle.

In this case, the radius of the circle is 3 in.

Substituting this value into the formula, we get:

C = 2π(3 in)
C = 6π in.

Therefore, the circumference of the circle is 6π in.
