Question

surface area and volume formulas of right circular hollow cylinder​

Answer 1

Step-by-step explanation:

Aa = 2 π r a

Total Surface Area of Cylinder = 2 π r ( r + a)

Volume of a Oblique Cylinder = π r2 h = π r2 a sin x.

Curved Surface of hollow cylinder = 2 π h ( R + r)

Total surface area hollow cylinder = 2 π ( R + r) (h + R – r)

Volume of the material for hollow cylinder = π R2 h – π r2 h = π h ( R2 – r2 )
