The formula to find the volume of a cylinder is V=![\pi](https://tex.z-dn.net/?f=%5Cpi)
h
You square the radius which would be 9
Then multiply that by 7 which is the height and get 63
Since it is left in terms of pi you do not need to multiply by pi so you add the pi symbol to the end.
Then get 63

Answer:
Bob is 17 years old
Mary is 22 years old
Step-by-step explanation:
Mary's current age: m
Bob's current age: b
m + b = 39

b + 5 + b = 39
2b + 5 = 39
2b = 34
b = 17
m = 22
