Find the curved surface area and total surface area of a right circular cylinder whose height is 15cm and the radius of the base is 7cm. `(T a k e\ pi=(22)/7)`

Text Solution

Verified by Experts

Radius of cylinder `r=7cm`
Height of cylinder `h=15 cm`
Curved Surface Area`=2pirh`
`=2×(22/7)×7×15`
`=660cm^2`
Total Surface Area`=2pir(h+r)`
`=2times(22/7)times7(15+7)`
`=2times22times22`
`=968cm^2`
