ANSWER

Let,

Height of the right circular cylinder =H

Radius of the base of the cylinder =R

Therefore,

Volume of the cylinder, V=πR

2

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

2H

Therefore,

Required ratio =

V

V

=

πR

2H

=

=1:2

Therefore, the ratio of the volume of the new cylinder to that of the origional cylinder is 2:1.
