Since the diameter is 4,000 miles, this means that the radius is 2,000 miles (just take half of 4,000)

So

Start with the volume of a sphere formula

Plug in

Cube to get

Multiply and (you can use 3.14 for pi) to get

Multiply and to get

So the volume of the sphere with a radius of 2000 miles is 33,510,321,638.2911 cubic miles

This means that volume of Mars is 33,510,321,638.2911 cubic miles
