if the radius of the base of a right circular cylinder is melted, then find the ratio of the volume of the cylinder thus obtained to the volume of original cylinder.
i quite did not get the question.
so explain it as well.
thank you :)
BrainlyHulk:
plz mention about the radius properly
i have checked the question. this is confusing me too.
from where did you get....
u-like.. pg 191.

Let the radius of original cylinder br 'r'
New radius= (r/2)
So, Volumes= pi*r2*h
and pi*(r/2)2*h
Ratio= pi*r2*h/pi*(r2/4)*h
=> r2/(r2/4)
=> r2*(4/r2)
=> 1/4
Hope it helps..
Cheers!

how did you know how much the radius melted?
i have let it
u can take r/4 also radius
but that won't give the same ratio
their will be little difference
1/16 is much more than 1/4
yes
okay leave :) thank you for helping me. the question has got some mistake in it.
which class ur in

Answer:
actually it should not be melted but it should be halved. Grammatical mistake!!
