Question

The base radii of two cylinders are in the ratio 2:3 and their heights are in the ratio 5:3.The ratio of thier volume is

Answer 1

Volume of cylinder = pi ☓ r^2 ☓ h

➡️ Cylinder 1:

Vol = pi ☓ 2^2 ☓ 5 = 20 pi

➡️ Cylinder 2 :

Vol = pi ☓ 3^2 ☓ 3 = 27 pi

➡️ Ratio of cylinder 1 : cylinder 2 =

20 :27

Hence their volume are in the ratio 20 :27
