### 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 $=\frac{2}{3}\pi {{r}^{3}}$
