Question

ramana says the TSA of hemisphere is half of the TSA of sphere do u agree with ramans? why​

Answer 1

Answer:

I do not agree with Ramana because the TSA of a sphere is 4πr^2 but the TSA of a hemisphere is 3πr^2. This is because the TSA of hemisphere gives the area of the curved side as well as flat side, while in sphere, there is no flat side.

This answer is correct if you think about it.

Pls mark as brainliest..

Answer 2

Answer:

NO

Step-by-step explanation:

BECAUSE, TSA OF HEMISPHERE= 3πr^2

AND, TSA OF SPHERE I= 4πR^2

3πR^2 IS NOT 1/2 4πR^2
