Problema Solution
a new cylindrical hydrocarbon storage tank,has a diameter of 100 feet and is 30 feet tall. calculate the volume of the tank's contents if it is filled to 90% of it's capacity.
Answer provided by our tutors
let
d = 100 ft the diameter of the cylinder
h = 30 ft the height
V = the volume of the cylinder
We need to find 90% of V
V = (d/2)^2 * pi * h
V = (100/2)^2 * pi * 30
V = 75,000 pi
90% of V is:
0.90*V = 0.90*75000*pi = 67,500 pi ft^3 = 211,950 ft^3
