Question

Find the circumference of the circle in terms of pi.

Answer 1

The answer is D. 78 pi inches

Answer 2

Answer:

Option: D is the correct answer.

 The circumference of the circle in terms of pi is:

                 D.   78π in.

Step-by-step 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:

$C=2\pi\times 39\\\\\\C=(39\times 2)\pi\\\\\\C=78\pi$

Hence, the circumference of circle is:

                     78π in.
