Find the volume of the bottom and top separately and then add them.

Cylinder volume is the area of the bottom times the height

(22/7) (5^2) •175=13750 ft^3

The volume of a sphere is

V = (4/3) (22/7) r^3

where r is the radius. Here that's also 5 since it fits on the cylinder.

Also we only want half the sphere so use

V = (2/3) (22/7) •5^3=261.9 ft^3

Which we round upto 262.

Now add the parts together

13750+262=14,012 ft^3
