Question

Find the circumference of the circle in terms of pi.

Answer 1

The answer is D. 78 pi inches

Answer 2

Option: D is the correct answer.

The circumference of the circle in terms of pi is:

D. 78π in.

Explanation:

We know that for a circle with radius r the circumference of the circle is given by the formula :

`Circumference(C)=2\pi r`

Here in the given figure we have: Radius (r)= 39 in.

Hence, the circumference of the given circle is calculated as:

`C=2\pi* 39\\\\\\C=(39* 2)\pi\\\\\\C=78\pi`

Hence, the circumference of circle is:

78π in.
