the radius of the base of a right circular cylinder is halved and the height is doubled . what is the ratio of the volume of the new cylinder to that of the original cylinder ? |
|
Answer» Step-by-step explanation: ANSWER Let, Height of the RIGHT circular cylinder =H Radius of the base of the cylinder =R Therefore, Volume of the cylinder, V=πR H Now, New height of the right circular cylinder H ′ =2H New radius of the base of the cylinder R ′ = 2 R
Therefore, New volume of the cylinder, V ′ =πR ′2 H ′
=π 4 R 2
2H Therefore, REQUIRED ratio = V V ′
= πR 2 H π 4 R 2
2H
= 2 1
=1:2 Therefore, the ratio of the volume of the new cylinder to that of the origional cylinder is 2:1. please follow me I will give your answer on time it's my promise to you |
