Multiple Choice

Solve the problem.
-A nuclear cooling tower cross section is a hyperbola having a diameter of $54 \mathrm { ft }$ at the center. The distance between the two foci is $92 \mathrm { ft }$ . What is the equation for the hyperbola?

A) $\frac { x ^ { 2 } } { 729 } - \frac { y ^ { 2 } } { 1387 } = 5$
B) $\frac { x ^ { 2 } } { 729 } - \frac { y ^ { 2 } } { 1389 } = 1$
C) $\frac { x ^ { 2 } } { 729 } - \frac { y ^ { 2 } } { 2116 } = 1$
D) $\frac { x ^ { 2 } } { 729 } - \frac { y ^ { 2 } } { 1387 } = 1$
