Question

If radius of a hemisphere is 2x , find its volume.

Answer 1

Hi Deepika!
_______________________________________________________________
Volume of Hemisphere= 2/3πr3

 Radius = 2x(Given)

So, Volume of Hemisphere= 2/3 x 22/7 x( 2x)³
                              
                                             = 2/3 x 22/7 x 8x³

                                             =352/21 x³ (unit)³

Answer 2

Volume of a hemisphere of radius x = (4/3)πx³.

Volume of a hemisphere is half = (2/3)πx³.

Here the radius is specified as 2x.

Therefore, by substituting this into the formula, we get:-

(2/3π) * (2x)³

= 16/3 π x³ Ans.
