A right circular cylinder of radius r ...

A right circular cylinder of radius `r` and height `h\ (h gt 2r)` just encloses a sphere of diameter (a) `h` (b) `r` (c) `2r` (d) `2h`

Text Solution

Verified by Experts

Cylinder radius `= r`

Height of the cylinder `= h`

`= 2r`

Sphere diameter = cylinder height

`d= h= 2r`

`d=2r`
