What is the formulae to take the volume of a hollow cylinder
Height=3 cm, Radius=1.25 cm
plzzzzzzzzzz help
Angella:
The above data given is insufficient to calculate the volume. So, I didn't provide my answer with any sort of calculations. ;)
but what is inner radius and outer radius
Every hollow cylinder has two surfaces, one inner and the other outer. The radius of the cylinder from the outer surface is the outer radius and the radius of the cylinder from the inner surface is the inner radius.

The formula for the volume of a hollow cylinder = πh(r₁² - r₂²)
where, h = height of the cylinder
r₁ = outer radius
r₂ = inner radius
where, h = height of the cylinder
r₁ = outer radius
r₂ = inner radius
