Answer 1

$\textbf{\underline{\underline{Answer :-}}}$

__________________________

First, Archimedes imagined cutting a sphere into two halves – hemispheres. Taking one hemisphere gave him a shape with a flat surface to work with – easier than a sphere, and if he could find the volume of a hemisphere, doubling it would give him the volume of a sphere.
