The formula for calculating the volume of a hexagonal prism is to take the area of the hexagon, then multiply it by the height of the prism.
The answer will depend on what information you have.
Its Area = pi * (radius ^2 - height^2)
by ASR do you mean Area Specific Resistance?
Curved surface area of a hemisphere means only the bent part of it , i.e,the part which looks like half of a sphere. Total surface area of a hemisphere is the circular top of a hemisphere + curved surface area of a hemisphere. So the formula goes like this: Curved surface area of hemisphere= 2πr2 Total surface area of hemisphere= 2πr2 + πr2 = 3πr2
