Question

The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder​

Answer 1

d = 4cm

Explanation:

curved surface area (CSA) of cylinder =
`2\pi rh`

h = 28cm and CSA = 352
`cm^(2)`

`2\pi rh` = 352

2 *
`(22)/(7)` * r * 28 = 352

`r = (352*7)/(2*22*28)`

after calculating, you will get r = 2cm

so diameter = 4cm
