Question

The radi of two cylinders of the same height are in the ratio 4 :5, then find the ratio of their volumes.​

Answer 1

Answer:

16 : 25

Step-by-step explanation:

The step is shown in the above picture

Answer 2

Answer:

16/25

Step-by-step explanation:

volume of cylinder = π r^2 h

where r is radius and h is height of cylinder

r1/r2 = 4/5 given in the question

therefore V1/V2 = (r1/r2)^2 = (4/5)^2 = 16/25
