The diameter is 8, so the radius is 4 (cut the diameter in half)
r = 4
The height is h = 3
Plug this into the formula below which is the volume of a cylinder
V = pi*r^2*h
V = pi*4^2*3
V = pi*16*3
V = pi*48
V = 48pi <--- this is the exact volume in terms of pi
V = 48*3.14
V = 150.72 <---this is the approximate volume
V = 151 cubic cm is the approximate volume if we round to the nearest whole number
Answer: choice A
