Question

find the volume of hemisphere bof diameter 6r units ? anyone can answer me for this questions

Answer 1

Hi there !!!

We are given the diameter of the hemisphere as 6 r

So , its radius = $\frac{6r}{2}$
= 3 r

We know that the formula to calculate the volume of a hemisphere ,

Volume = 2/3πr³
             = 2/3 × 22/7 × (3r)³
             = 2/3 × 22/7 ×27 r³
             = 44 / 231 × 27 r³
             = 396 / 7 r³

Answer 2

Diameter of hemisphere is 6r
radius of the hemisphere will br 3r
volume of hemisphere = (2pi(3r)^3)/3 =(2x27xpixr^3)/3=2x9pixr^3=18pir^3
pi=3.14
