Important formulas:
for cylinder, V = ∏r2h
using circle, definition of ∏ = C/d
for circle, d = 2r
The problem gives values for C and h; what else is needed to find V?
V = r2h
V = ∏(d/2)2h [substitute r=d/2]
V = (∏d)(d)h/4 [re-group]
V = C(C/∏)(h/4) [substitute ∏d=C and d=C/π)
V = C2h / (4∏)
O.K., now, plug in the numbers (doing this later is much easier and more accurate):
V = (132)2(25) / (4*3.14)
V = 34681.53 cm3
I hope this will help you
if not then comment me

2πr=132
r=66/π
volume=πr²h
v=π•66•66/π² °25
=66•7•3•25
hope it helps you dear.
