How many solid cylinders of radius 6 cm and height 12 cm can by made by melting a solid sphere of radius 18 cm ?
Activity : Radius of the sphere , r=18 cm
For cylinder , radius R =6 cm, height H =12 cm
`therefore ` Number of cylinders can be made = `("Volume of the sphere")/(.....................)`
= `(4/3pir^3)/(.......)`
`= (4/3xx18xx18xx18)/(..................)`
=

Explanation

Volume of a cylinder , `piR^@H`, 6 x 6 x 12 , 18
