Find the (i) curved surface area (ii) ...

Find the (i) curved surface area (ii) total surface area and (iii) volume of a right circular cylinder whose height is 15cm and the radius of the base is 7cm.

Text Solution

Verified by Experts

1) curved surface area of a right circular cylinder `=2xxpixxrxxh`
`=2xxpixx7xx15`
`=660cm^2`
2)total surface area`=2xxpixxrxxh+2xxpixxr^2`
`=2pixx7xx15+2xxpixx7^2`
`=660+308`
`=968cm^2`
3)volume of cylinder`=pixxr^2xxh`
`=pixx7^2xx15`
`=2310cm^3`
