Question
The volume (in cm3) of the greatest sphere that can be cut off from a cylindrical log of wood of base radius 1 cm and height 5 cm is
Options
`4/3 pi`
`10/3 pi`
5π
`20/3 pi`
Solution
`4/3 pi`
Explanation;
Hint:
Radius of the sphere = 1 cm
Volume of the Sphere = `4/3` πr3 cu.units
= `4/3 xx pi xx 1 xx 1 xx 1 "cm"^3`
= `4/3` π cm3
