*         Surface Area of Hemisphere

It is obtained by cutting the plane through the centre of a sphere into two equal parts and each part is known as the hemisphere.

The curved surface area of the hemisphere \[=2\pi {{r}^{2}}\]

The total surface area of the hemisphere \[=3\pi {{r}^{2}}\]

Volume of the hemisphere \[=\frac{2}{3}\pi {{r}^{3}}\]
