Express the formula \( V = \pi r ^ { 2 } . H \) in terms of the height, \( H \) . Use that formula to find the height when the volume is \( 45 \pi \) and the radius is \( 3 . \) 

(A)\( H = \frac { V } { 2 \pi r } ; H = 7.5 \) 

(B)\( H = \frac { V } { \pi r } ; H = 15 \) 

(C)\( H = \frac { V } { \pi } - r ^ { 2 } ; H = 30 \) 

(D)\( H = \frac { V } { \pi r ^ { 2 } } ; H = 5\)
