Question

The radius & height of a cylinder are in the ratio 1:2. If its volume is 54π , find its curved surface area in terms of π.

Answer 1

Answer:

Step-by-step explanation:

radius = r

height = 2r

Volume = pi r^2 h

54 pi = pi r^2 * 2r

=> 27 = r^3

=> r = 3

CSA = 2 pi r h

= 2* pi *3 * 6

= 36pi
