for the given cylinder
r=(r÷2)
h=2h
V=π(r^2)h=π(r^2 ÷ 2^2)2h
=π(r^2 ÷ 4)2h
=π(r^2 ÷ 2)h
thus for the revised cylinder
volume is. pi r upon 2 h
r=(r÷2)
h=2h
V=π(r^2)h=π(r^2 ÷ 2^2)2h
=π(r^2 ÷ 4)2h
=π(r^2 ÷ 2)h
thus for the revised cylinder
volume is. pi r upon 2 h

previous
radius=r
height=h
after changing
radius=r/2
height=2h
previous volume=πr^2h
volume now=π{r^2/4)(2h)
πr^2h/2
Answer= half of previous volume
sorry for late answer I had network problem
