Question

The radii of two cylinders are in the ratio of 2 ratio 3 and the Heights are in the ratio of 9 ratio 4 calculate the ratio of their volume​

Answer 1

Volume of cylinder = πr²h

Given :

» r1/r2 = 2/3 and h1/h2 = 9/4

Solution:

» V1 / V2 =(π r1² h1) / (π r2² h2)

» V1 / V2 = (4 × 9) / (9 × 4)

» V1 / V2 = 1

Answer 2

Step-by-step explanation:

As radii of two cylinder in in ratio of 2:3

So radius of 1st cylinder=2r

radius of 2st cylinder=3r

heights are in the ratio 5:3.

height of 1st cylinder=5h

height of 2st cylinder=3h

ratio of volume=volume of 1st cylinder/volume of 2nd cylinder

V=Π(2r)

2

∗5h/Π(3r)

2

∗3h

V=20rh/27rh

V=20/27
