Solve the problem.
-The radius of a sphere is given by the formula $r = \sqrt { \frac { S } { 4 \pi } }$, where $S$ is the surface area. If the surface area is 9598 square inches, what is the radius? Use $3.14$ for $\pi$, and round your answer to the nearest tenth of an inch.
A) $49 \mathrm { in }$.
B) 0 in.
C) $86.8$ in.
D) $27.6 \mathrm { in }$.

The radius $r$ can be found by substituting $S = 9598$ square inches and $\pi = 3.14$ into the formula $r = \sqrt { \frac { S } { 4 \pi } }$, resulting in $r = \sqrt { \frac { 9598 } { 4 \times 3.14 } }$ which simplifies to approximately $27.6$ inches.
