The radius of a sphere depends on its surface area, $S$, and is given by the formula
$r=\sqrt{\frac{\mathrm{S}}{4 \pi}}$.
What is the surface area of a sphere with radius of 8.8 inches?
Use 3.14 for $\pi$. Round to the nearest tenth of a square inch.
A) 110.5 square inches
B) 972.6 square inches
C) 243.2 square inches
D) 27.6 square inches

The surface area, $S$, of a sphere is given by the formula $S = 4\pi r^2$. Substituting $r = 8.8$ inches and $\pi = 3.14$, we get $S = 4 \times 3.14 \times (8.8)^2 = 4 \times 3.14 \times 77.44 = 972.6$ square inches.
