what is the meaning of the inner and outer radius of the hollow sphere ?

A hollow sphere has nothing but vacuum inside. So we can find two surface areas. One the outer surface area and another the is inner surface area. The same way you have two diameters, one extending from outer surface to outer one. And another from inner to inner. This is made by the thickness of the wall of the Sphere.
If you say, volume of a hollow sphere.., it'll be the volume of the hollow part of it, which can be given by,
V = 4/3 * pi * (inner radius, r)^3
If you are about to calculate the volume of the wall, (i.e., the matter in it..), it is given by
V = 4/3 * pi * (outer radius, R)^3 - 4/3 * pi * (inner radius, r)^3
Or
If you wanna calculate the volume as such of the sphere,
Go with
V = 4/3 * pi * (outer radius, R)^3
Got something..???!!

Poke a hollow in it. Fill it with water. Pour the water right into a measuring cup. bear in mind ways plenty water there is in accordance to the markings on the cup. that's how plenty quantity replaced into interior the sector.

(4/3)*pi*(r)^3
where r is the inner radius.

fill it with water and measure the water
