Question

If the area of a circle is 58 square feet, find the circumference.

Answer 1

Set up the equation first:

Area =
$\pi {r}^{2}$
Circumference =
$2\pi \: r$
Solve for r using the area equation:
$58 \div \pi = {r}^{2}$
r = 4.297

Now the circumference
$2\pi(4.297)$
C = 26.997

Therefore your answer is B

Answer 2

The answer is almost certainly b.
