The volume of a hemisphere is given by the formula 4 x pi x r3/6, where r is the radius and pi is approximately 3.1416
Because it is a hemisphere
Calculate the radius (it is half the diameter).Use the formula for a sphere: area = 4 x pi x radius2.Since a hemisphere is half a sphere, divide this result by 2.Question:Do you mean the surface area to include the flat face of the hemisphere?If so then follow the above instructions and add pi*42 to your answer which will give you the complete surface area of the hemisphere.
The answer for the hemisphere is half the volume of a sphere, which is given by the formula (2/3)πr³, where r is the radius. The surface area of a hemisphere is half the surface area of a sphere, given by the formula 2πr².
The formula for calculating the volume of a hemisphere is (2/3)πr^3, where r is the radius of the hemisphere. To calculate the volume of a smaller part of the hemisphere, you would need to multiply the total volume of the hemisphere by the fraction of the hemisphere being considered.
To find the surface area of a hemisphere, you can use the formula: SA = 2πr^2, where r is the radius of the hemisphere. This formula takes into account the curved surface area of the hemisphere.
The volume of a hemisphere is equal to two thirds times pi times the radius cubed.

The volume of a hemisphere is given by the formula 4 x pi x r3/6, where r is the radius and pi is approximately 3.1416
Formula for calculating the area of a hemisphere... Area = (4 x pi x r2) / 2
A hemisphere is a three-dimensional shape that consists of a half-sphere. It has a curved surface and a flat base. The formula for the volume of a hemisphere is V = (2/3)πr^3 and for the surface area is A = 3πr^2.
The surface area of a sphere can be found with the formula 4pi * r2. Assuming the hemisphere is exactly half of a sphere, the surface area of a hemisphere can be found using the formula A = 2pi * r2 + pi * r2 Which can be written as A = pi(3r2) 942cm/pi = 3r2 314cm/pi = r2 r = 10cm (approximately) The radius of the hemisphere is approximately 10cm.
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
