Question

what is surface area and volume of an hollow cylender​

Answer 1

Hii...

Here's your answer ......

Surface are of Cylinder =

$2\pi \: rh$

Total surface area of Cylinder =

$2\pi \: r \: ( r+h )$

and volumn of Cylinder =

$\pi {r}^{2} h$

Hope it will help you....

Thanks for asking☺️☺️....

Answer 2

Answer:

Hollow cylinder

Surface area = 2π (Rh + rh + R^2 - r^2)

or, 2π (r+ r) h + 2π (R^2 - R^2)

Volume = π (R^2 - r^2)
