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

First, you set 58= 3.14 (pi) r^2. Solving for r you get about 4.3ft. You then use this radius in the circumference equation, C=2 3.14(pi) r. 2x3.14x4.3=27.004ft. I rounded a few times along the way so your answer is B.
