Find the volume of a hemisphere of diameter 12 cm (Use  π = 227\frac{22}{7})

Show answer & explanation

Correct answer: A

Explanation

The Correct answer is option 1 i.e  31687\frac{3168}{7} cm3​​​​​​.

The diameter of the hemisphere = 12 cm

So, radius = 12/2 = 6 cm

The volume of the hemisphere = 2/3 πr3

= 23×227×63\frac{2}{3}\times\frac{22}{7}\times6^3

= 31687\frac{3168}{7} cm3​​​​​​
