Solve the Problem $y = \frac { 28 } { \sqrt { 49 + x ^ { 2 } } }$

Multiple Choice

Solve the problem.
-An oil storage tank can be described as the volume generated by revolving the area bounded by $y = \frac { 28 } { \sqrt { 49 + x ^ { 2 } } }$ , $x = 0 , y = 0 , x = 2$ about the $x$ -axis. Find the volume (in $\mathrm { m } ^ { 3 }$ ) of the tank.

A) $97.9 \mathrm {~m} ^ { 3 }$
B) $24.5 \mathrm {~m} ^ { 3 }$
C) $0.874 \mathrm {~m} ^ { 3 }$
D) $714 \mathrm {~m} ^ { 3 }$
