Question

The Surface area of a solid sphere is 1256 sq.cm .It is cut into hemispheres. calculate the volume of a hemisphere

hint Hint:

Volume of sphere $equals 4 over 3 pi r cubed$

The correct answer is: 2093.66cm3

Explanation:

We have given surface area of solid sphere 1256cm².It cut into hemispheres.

We have find the volume of that hemisphere.

Step 1 of 1:
It is given that surface area of solid sphere 1256cm².
So,
4πr² = 1256
r² = 100
r = 100
So, The volume of the hemisphere will be
$equals 2 over 3 pi r cubed$
$equals 2 over 3 pi left parenthesis 10 right parenthesis cubed$
= 2093.66cm³
