If the dinner cost 85 you multiply by .30 and you get 25.5. If you wanna find out whole cost after subtract 25.5 from 85.
To find the volume of a cylinder, the equation used is V = 3.14r^2h
r = 4, and h = 3, so we input both numbers to get V = 3.14*4^2*3
V = 3.14*4^2*3 = 3.14*16*3 = 3.14*48=150.72
V = 150.7 ft^3
