Find the curved surface area and total surface area of a cylinder, the diameter of whose base is 7cm and height is 60cm.

Explanation

Diameter of the base of cylinder = `7cm`
Radius `(r) = 7/2 cm`
Height `(h) = 60cm`
Curved surface area=`2pirh`
`2xx7/2xx7/2xx60cm^2`
`1320cm^2`
Total surface area =`2pir(h+r)`
`2xx22/7xx7/2(60+7/2)`
`22(127/2)`
`11xx127cm^2`
`1397cm^2`
