Answer:
Only Choices A and C make sense.
Step-by-step explanation:
Height of cylinder = 12 feet.
We do not know radius.
V = (pi)*r^2 * h = (pi)*(r^2) * 12
A.) r = 7 feet V = 588*pi cubic feet
check this: V = (pi) * (7^2) * 12 = (pi)*49*12 = 588π cubic ft.
A works.
B.) V = 192(pi) r = 2 ft. check this: V = (pi)*(2^2)*12 = 48(pi) not 192(pi)
NOT B.)
C.) V = 768(pi) diameter d = 16 feet
Check this: V = (pi)*(8^2)*12 = 768(pi)
C works.
D.) diameter d= 5 ft. V = 300(pi) cubic ft.
Check this: V = (pi)*(5/2)^2 *12 = (pi)* (25/4) * 12 = (pi)*25*3 = 75(pi) cubic feet.
NOT D.
