The radius of base of a cylinder is 7 cm and height is 10 cm. Find its curved surface area and volume.

Text Solution

Verified by Experts

Radius of the base of cylinder r = 7 cm, height h = 10 cm
`therefore` Curved surface area of cylinder `=2pi rh`
`=2xx(22)/(7)xx7xx10`
`=440 cm^(2)`
and volume `=pi r^(2)h`
`=(22)/(7)xx7xx7xx10`
`=1540 cm^(3)`
