Let a cylinder be with height h ,its inner and outer radii be r andR respectively.
Now,its TSA=2pirh +2piRh+2pi(R2+r2)
Rashmi Bajpayee 8 years, 9 months ago
TSA of hollow cylinder
= 2πRh + 2πrh + 2(πR2 - πr2)
= 2π[Rh + rh + (R + r)(R - r)]
= 2π[h(R + r) + (R + r)(R - r)]
= 2π(R + r)(h + R + r)

Ans. T.S.A of hollow cylinder = {tex}2\pi h(R+r){/tex}
Where R is outer radius and r is inner radius of hollow cylinder.
