Question

Radius of hemisphere 2d/ 3 then find the volume

Answer 1

Step-by-step explanation:

$Given: \: r \: = \frac{2d}{3} \\ volume \: of \: hemisphere \: = \\ = \frac{2}{3} \pi \: {r}^{3} \\ = \frac{2}{3} \pi \:( \frac{2d}{3} ) ^{3} \\ = \frac{2}{3} \pi \: \frac{8 {d}^{3} }{27} \\ = \frac{16 \: \pi \: {d}^{3} }{81} \\ = \frac{16}{81} \pi \: {d}^{3}$
