Answer:
2 2/3 cm
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the volume =96 pi and the diameter is 12
We want the radius
r =d/2 = 12/2 =6
96 pi = pi * (6)^2 h
96 pi = 36 pi h
Divide each side by 36 pi
96 pi/36 pi = 36pi h / 36 pi
8/3 = h
Changing from an improper fraction to a mixed number
2 2/3 = h
Rational of course, because
and both 3 and 5 are relatively prime integers.
