Question

find the radius of a hemisphere with csa 1232m²​

Answer 1

Answer:

14 m

Step-by-step explanation:

CSA of Hemisphere=2πr²

Here it is given that CSA=1232m²

So, 2πr²=1232m²

=>2×22/7×r²=1232m²

=> r²=1232m²×7/44

=> r²=2156/11 m²

=> r²=196 m²

=> r=√196 m²=14 m

Therefore, Radius of the hemisphere is 14 m.
