A sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed.

A sphere with height h and radius r. A cylinder with height h and radius r.

What is the volume of the sphere?
6 meters cubed
7 meters cubed
14 meters cubed
28 meters cubed

Step-by-step explanation:

Volume of cylinder V1=πr²h

for sphere h=r

so for cylinder also h=r(∵ both have same h)

V1=πr²×r=πr³=21

volume of sphere V2=4/3 πr³=4/3×21=28 meters cubed.
