A spherical ball is divided into two equal halves. If the curved surface area of each half is 56.57cm2,find the volume of the spherical ball.

CSA of 1 hemisphere= 56.57cm2
2 pi r2 = 56.57
r2= 56.57/3.14×2
r2= 9.005
r=/9.005
r= 3.00.....cm2

vol of sphere= 4/3 pi r3
= 4/3 3.14× 3×3×3
= 4×3.14×3×3
=113.04 cm3 approximately.
