Answer:
The volume of the hemisphere
V = 121.33086 cubic centimeter
Step-by-step explanation:
<u>Step(i)</u>:-
Given that the total surface area of a hemisphere = 45π cm²
<em> The total surface area of a hemisphere = 3π r²</em>
Equating
3π r² = 45π
r =
The radius of the sphere 'r' = 3.87
<u><em>Step(ii):-</em></u>
<em>The volume of the hemisphere</em>
we know that π = 3.14
V = 121.33086 cubic centimeter
