Question

Calculate the curved surface area of a cylindrical drum whose dimensions are diameter 5cm, height 30cm​

Answer 1

150
`cm^(2)`

Explanation:

Curved surface area of a cylinder = 2
`\pi rh`

Radius=
`(5)/(2)\\`cm

Height=
`30`cm

Curved surface area of a cylinder=
`2\pi rh`

= 2 x
`(5)/(2)` x 30

= 150
`cm^(2)`
