Question

*If the ratio of the heights of two cylinders with equal radius is 3: 5, what is the ratio of their volumes?*

1️⃣ 9:25
2️⃣ 25:9
3️⃣ 3:5
4️⃣ 5:3​

Answer 1

Answer:

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

Answer 2

Answer:

option 3️⃣ 3:5

This is the right answer for your question.
