Hemisphere Volume, Curved Surface Area and Total Surface Area Formula

Let the radius of a hemisphere be r, Then,
\begin{aligned}
\text{Volume of Hemisphere =} \left( \frac{2}{3} \pi r^3 \right) \text{cubic units} \\

\text{Curved Surface area of Hemisphere =} \left( \frac{2}\pi r^2 \right) \text{sq. units} \\

\text{Total Surface area of Hemisphere =} \left( 3 \pi r^2 \right) \text{sq. units} \\
\text{Please remember 1 litre = }1000 cm^3
\end{aligned}
