The two hemispheres make one whole sphere of radius 3, so
its volume = (4/3)π(27) = 36π ft^3
the cylinder part also has a radius of 3 and a length 14 , (20 - 2 radii)
so its volume = π(9)(14) = ..... ft^3
add them up
Please help me!! i really don't know how to do it. can someone show me how to do it.
A propane gas tank consists of a cylinder with a hemisphere at each end. Find the volume of the tank if the overall length is 20 feet and the diameter of the cylinder is 6 feet (round to an exact number) (see figure in the website below).

length = 20 = cylinder length + 2 R = L + 6
so L = 14 feet
volume = sphere volume + cylinder volume
= (4/3) pi (3)^3 + pi (3)^2 * 14
= 36 pi + 126 pi
so L = 14 feet
volume = sphere volume + cylinder volume
= (4/3) pi (3)^3 + pi (3)^2 * 14
= 36 pi + 126 pi
@Reiny and @Damon thanks, so my answer is 36 pi + 126 pi = 508.94
yes
thanks guys
