Answer:
V≈471.24
r Radius: 5
h Height: 6
Step-by-step explanation:
This is an exponential growth problem. Exponential growth can be expressed mathematically in the following way:

.
Parameter a presents initial amount.
Parameter r is percentage increase.
Parameter t is time.
An equation that would describe given problem is:

t is the time in years.
