SSC CPO 2024 PYQ — Question 111

The correct answer is option 2 i.e. 12219.43.

Given that, radius of hemisphere = 18 cm

Volume of hemisphere = ${2 \over 3} \pi r^3$

According to the given question,

⇒ Volume = ${2 \over 3}\times {22 \over 7}\times 18^3$

⇒ ${2 \over 3}\times {22 \over 7}\times 18\times 18 \times 18$ = 12219.4285 ≈ 12219.43 cm³

Hence the volume of the hemisphere (in cm³) is 12219.43.
