Question

if the radius of the base of two circular cylinder are in the ratio 3 ratio 4 are their height are in the ratio 6 ratio 5 find the ratio of their curved surface area​

Answer 1

Answer:

Step-by-step explanation:

In cylinder 1

Radius=3x

Height=6y

CSA=2πrh=36πxy

In cylinder 2

Radius=4x

Height=5y

CSA=2πrh=40πxy

CSA 1:CSA 2=36πxy:40πxy

=9:10

Answer=9:10
