Learn how to calculate the volume of a cylinder. The difference of the external and internal radius forms wall thickness of a cylinder ie. V phr 1 2 r 2 2.
Length or Height h in mm.
Hollow cylinder volume p R 2 r 2 h pi times R2 - r2 times h p R 2 r 2. Radius R in mm. V phr 1 2 r 2 2. Volume of a cylinder ph r12 r22 Where r 1 external radius and r 2 internal radius of a cylinder.
