Question

20. Find the ratio of volume of a cone and a volume of a cylinder of equal diameter and of equal height
SECTION-B​

Answer 1

Answer:

let the height be h

and diameter be 2r

therefore, radius = r

(for both the shapes i.e., cone and cylinder)

For cone,

volume =1/3×πr^2h

For cylinder,

volume=πr^2h

Now, volume of cone÷volume of cylinder =1/3×πr^2h÷πr^2h

=> 1/3

Therefore,the required ratio is 1:3
