<PRE><B>Question 169858</B>
The fuel tank on a diesel truck is a cylinder with a diameter of 28 inches measuring 3 feet long. If 231 cubic inches is the same as a gallon of diesel fuel, how many gallons of diesel fuel would be required to fill the tank? Round answer to the nearest gallon.
----------------------
{{{V = pi*r^2*h}}} (h is the 3 ft length)
{{{V = pi*14^2*36}}} (3 ft = 36 inches)
{{{V = 7056pi}}} cubic inches
{{{V = 7056pi/231}}} gallons
V = 96 gallons
