Question:

Find the volume of a solid hemisphere whose radius is 0.7 m.  $\left(\pi=\frac{22}{7}\right)$

Options:

71.86 m3

7.186 m3

0.7186 m3

00007186 m3

Correct Answer:

0.7186 m3

Explanation:

volume of a solid hemisphere = \(\frac{2}{3}\)πr³

= \(\frac{2}{3}\) ×  \(\frac{22}{7 }\) × 0.7 ×0.7 ×0.7

= 0.7186

The correct answer is Option (3) → 0.7186 m3
