Question

If the radius of the cylinder is doubled and height of the cylinder is halfed. Then find out the ratios of their volumes

Answer 1

Answer:

1/2

Step-by-step explanation: volume = πr^2h

New volume π(4r^2)h/2 =2(πr^2h)

Please give brainliest thanks

Answer 2

Case-1

Radius = r

Height = h

Volume = πr²h

Case-2

radius = 2r

height = h/2

volume = π(2r)²*h/2

            = 2πr²h

So, the ratio of the volumes_

πr²h : 2πr²h

= πr²h/2πr²h

= 1/2

= 1:2

So, the ratio is 1:2.
