Multiple Choice

Solve the problem. Round your answer, if appropriate.
-The volume of a sphere is increasing at a rate of $7 \mathrm {~cm} ^ { 3 } / \mathrm { sec }$ . Find the rate of change of its surface area when its volume is $\frac { 4 \pi } { 3 } \mathrm {~cm} ^ { 3 }$ . (Do not round your answer.)

A) $14 \mathrm {~cm} ^ { 2 } / \mathrm { sec }$
B) $\frac { 28 } { 3 } \mathrm {~cm} ^ { 2 } / \mathrm { sec }$
C) $14 \pi \mathrm { cm } ^ { 2 } / \mathrm { sec }$
D) $\frac { 1 } { 3 } \mathrm {~cm} ^ { 2 } / \mathrm { sec }$
