What is hollow cylinder and oblique cylinder
Answers
he example of hollow cylinders is pipes, circular buildings and bearing bushes, etc. If RR is the outside radius of the cylinder and rr is the inside radius of the cylinder, then (i)V=πR2h−πr2h=π(R2−r2)hV=πR2h−πr2h=π(R2−r2)h
(ii) V=π4(D2−d2)V=π4(D2−d2)
DD and dd being outer and inner diameter, VVis volume.
An oblique cylinder is a cylinder, where the two circular end planes are parallel to each other, but unlike the right circular cylinder the lateral surface (the curved surface) is not perpendicular to the end planes.
Area and volume of an oblique cylinder
The volume of an oblique cylinder can be calculated in two ways.
If the length (a) of the lateral surface is given:
If the cylinder’s height (h) is given:
The area of the lateral surface of an oblique cylinder
If the length (a) of the lateral surface is given:
If the cylinder’s height (h) is given:
Area of the entire surface of an oblique cylinder
First you calculate the area of the lateral surface with the formula above, and then you add the area of the two circular end planes calculated with the formula:
