Radius he r and height be h
- r1=r2=r
- 2h1=h2
[tex]\\ \tt\longmapsto \dfrac{v1}{v2}=\dfrac{\dfrac{1}{3}\pi r^2h}{\pi r^22h}[/tex]
- Cancel πr^2
[tex]\\ \tt\longmapsto \dfrac{v1}{v2}=\dfrac{1/3}{2}[/tex]
[tex]\\ \tt\longmapsto v1:v2=1:6[/tex]
Cylinder has 6times more volume

For cylinder
- r=15cm
- h=30cm
[tex]\\ \tt\longmapsto V=\pi r^2h=\pi 15^2(30)=225(30)\pi=6750\pi cm^3[/tex]
For sphere
- r=15cm
[tex]\\ \tt\longmapsto V=\dfrac{4}{3}\pi r^3=\dfrac{4}{3}\pi 15^3=\dfrac{13500\pi }{3}=4500\pi cm^3[/tex]
- Volume left=6750-4500=2250cm^3
