Question

If radii of two cylinder are in ratio 4:3 and their heights are in ratio 5:6 .find the ratio of their curved surfaces

Answer 1

Answer:2:3

Step-by-step explanation:

The radii of two cylinders are in ratio 4:3

Their heights are in the ratio 5:6

Let the ratio be x.

So radii are 4x and 3x

Heights are 5x and 6x

Formula of curved surface area of cylinder :

2πrh

So, the ratio of their curved surfaces:

2π(4x)(5x)/2π(5x)(6x)--> 4/6-->2/3

Hence the ratio of their curved surface area is 2:3

Answer 2

Answer:

answer is 2:3

Step-by-step explanation:

radii of first cylinder is 4x

height of first cylinder is 5x

radii of 2nd cylinder is 3x

height of 2nd cylinder is 6x

use formula of curved surface area of cylinder =2πrh

2π×4x×3x/2π×3x×6x

by cutting it's answer becomes 2:3
