Question

the radii of two cylinder are in the ratio of 2:3 and their height are in the ratio of 5:3. find the ratio of their volume​

Answer 1

Answer:

The radii of two cylinders are in the ratio 2:3 and their heights are in the ratio 5:3 so volume will be 20:27

Answer 2

Answer:

(Volume of cylinder 1)

(Volume of cylinder 2)

= π(2×)² 5y

π(3×)² 3y

= 20

27

(Surface area of cylinder 1)

(Surface area of cylinder 2)

= 2π×2x×5y

2π×3x×3y

= 10
