Question 1086014: A propane gas tank has the shape of a right circular cylinder with a hemisphere on each end. If the cylinder part of the tank is 4 ft. long (not including the hemispheres) and the diameter is 9 ft. Find the volume of the tank. Use 3.14 for pi. I used pir²h for the cylinder and 4/3pir³ for the hemisphere.I came up with V=635.85ft³

A propane gas tank has the shape of a right circular cylinder with a hemisphere on each end. If the cylinder part of the tank is 4 ft. long (not including the hemispheres) and the diameter is 9 ft. Find the volume of the tank.
------------------
r = 4.5
Cyl: Vol = pi*r^2*h = 254.469 cuft
Sphere: Vol = 4*pi*4.5^3/3 = 381.7 cu ft
--> 636.17 cu ft (using the Pi button)
