Complete this activity and find volume of a hemisphere having radius 30cm.( π = 3.14)​

Answer» ONG>Step-by-step explanation:

Volume of HEMISPHERE =

\frac{2}{3} \pi {r}^{3}

Here, RADIUS of hemisphere, r = 30 cm

Volume =

\frac{2}{3} \pi ({30})^{3} \\ = \frac{2}{3} (3.14) ({30})^{3} \\ = \frac{2 \times 3.14 \times 30 \times30 \times 30}{3} \\ = 2 \times 3.14 \times 10 \times 30 \times 30 \\ = 6.28 \times 9000 \\ = 56520 {cm}^{3}
