Find the volume and curved surface of a ...

Find the volume and curved surface of a sphere whose diameter is 6 cm.

Text Solution

Verified by Experts

Here, 2r = 6
`rArr r - 3 cm`
`therefore` Volume of shpere `=(4)/(3)pi r^(3)=(4)/(3)pi(3)^(3)`
`= 36pi cm^(3)`
and curved surface `= 4pi r^(2)`
`= 4 pi (3)^(2)`
`= 36 pi cm^(2)`
