Answer:

$C=9.4\pi$ meters

Step-by-step explanation:

Recall to find the circumference of a circle the formula is $C=\pi d$ or $C=2\pi r$ .

We start by substituting 4.7m for r in the second circumference formula.

$C=2\pi r\\C=2\pi (4.7)\\C=9.4\pi$ . We input this value of r into the area formula.
