Volume of Solids
The volume of the combined figures is obtained by finding the volume of each part separately and then adding them together.
Cylinder
If 'r' be the radius and 'h' be the height of the cylinder, then
Volume of the cylinder \[=\,\pi \,\,{{r}^{2}}h\]
Cone
If 'r' be the radius and 'h' be the height of the cone, then
Volume of the cone \[=\frac{1}{3}\pi {{r}^{2}}h\]
Sphere
If 'r' be the radius of the sphere, then
Volume of the sphere \[=\frac{4}{3}\pi {{r}^{3}}\]
Hemisphere
If 'r' be the radius of the hemisphere, then
Volume of the hemisphere \[=\frac{2}{3}\pi {{r}^{3}}\]
