What is the volume of a hemisphere having a diameter of 16.8 cm? (Take $\pi ={22\over7}$ )

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 1241.856 cm³.

Radius = 16.8/2 = 8.4 cm

Volume of hemisphere = ${2\over3}\pi r^3$

⇒ ${2\over3}×{22\over7}× (8.4)^3$ = 1241.856 cm³
