How many solid cylinders of radius 6 cm ...

How many solid cylinders of radius 6 cm and height 12 cm can be made by melting a solid shpere of radius 18 cm ?
Radius of the sphere, `r= 18 cm`
For cylinder, radius R = 6 cm, height H = 12 cm.
`:.` Number of cylinder can be made

Text Solution

Verified by Experts

Radius of the sphere, r = 18 cm
For cylinder, radius R = 6 cm, height H = 12 cm.
`:.` Number of cylinders can be made `=("Volume of Sphere")/("Volume of each cylinder")`
`(4/3pir^3)/(piR^2H)`
`=(4/3xx18xx18 xx18)/(6xx6xx12)`
= 18
