Question

What is the ratio of volume of a sphere to that of a hemisphere of a same radius?

​

Answer 1

Answer:

Step-by-step explanation:

So volume of hemisphere=1/2 of the volume of the sphere.

So volume of sphere=4/3*π*r^3

Volume of hemisphere=2/3*π*r^3

So the ratio will be:

(4/3*π*r^3)/(2/3*π*r^3)=2

Note: there is no change in the radius. If the radius of the hemisphere was given to be fair of the sphere then the answer will be different.

Hope this helps you and please mark it as the brainliest.
