Question

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

A. 4.25 ft.
B. 26.99 ft.
C. 42.5 ft.
D. 22.35 ft.

Answer 1

the answer is almost certainly b.

Answer 2

Set up the equation first:

Area =

`\pi {r}^(2)`
Circumference =

`2\pi \: r`
Solve for r using the area equation:

`58 / \pi = {r}^(2)`
r = 4.297

Now the circumference

`2\pi(4.297)`
C = 26.997

Therefore your answer is B
