Question

The curved surface area of a cylinder is 192π cm2. If its height and radius are in the ratio 2 : 3, find its height

Answer 1

Answer:

Since,given CSA of a cylinder is 192

$\pi$cm².

Also given ratios of its height and radius is 2:3.

let height and radius be 2x and 3x

And we know that CSA if cylinder is 2

$\pi$

rh

it implies 6x²×2=192

it implies x=4

it implies height =8cm
