Solve the problem.
-The radius of a sphere depends on its surface area, S, and is given by the formula $\mathrm{r}=\sqrt{\frac{\mathrm{S}}{4 \pi}}$.
What is the surface area of a sphere with radius of 8.6 inches? Use 3.14 for $\pi$.
A) 108 square inches
B) 232.2 square inches
C) 27 square inches
D) 928.9 square inches

Question

Quizplus · Accepted Answer

To find the surface area $ S $, use the formula $ S = 4\pi r^2 $. Substituting $ r = 8.6 $ and $ \pi = 3.14 $, we get $ S = 4 \times 3.14 \times (8.6)^2 = 928.9 $ square inches.
