A one half of a sphere is called a hemisphere.
Volume of a hemisphere:
Let r be the radius of a sphere.
Volume of a hemisphere = \times Volume of a sphere
=
=
Volume of a hemisphere = cu. units

Example:
The radius of the hemisphere is 14 \ cm. Find the volume of the hemisphere in grams if 1 \ cm^3 = 0.4 \ g.
Solution:
Radius of the hemisphere (r) = 14 \ cm
Volume of the hemisphere = cu. units
=
=
= 5749.33 cm^3
Now, convert cm^3 to g.
1 \ cm^3 = 0.4 \ g
5749.33 \ cm^3 = 5749.33 \times 0.4 = 2299.732 \ g
Therefore, the volume of the hemisphere is 2299.732 \ g.
Important!
The value of \pi should be taken as unless its value is shared in the problem.
