Question

A right circular cylinder of radius r cm and height h cm (h>2r) just encloses a sphere. Find diameter of sphere.

Answer 1

Answer:

2r

Step-by-step explanation:

the sphere is enclosed in the cylinder

The maximum diameter it can take will be that of the shortest dimension.

Given that h > 2r

The diameter of the sphere will be the diameter of the cylinder

Diameter of the cylinder = 2 x radius = 2r

Therefore the diameter of the sphere = 2r

Answer: The diameter of the sphere is 2r

Answer 2

Answer:

2r
