A spherical ball of radius 8 cm is to be divided into eight equal part
Right Answer is: B
After being cut, the ball will have eights parts of equal volume and surface area.
Area of ACBD = Surface area of ball = = 32π
And DOCB is half circle, so its area = = 32π
Now, Surface area of each piece = Area of ACBD + 2 (Area DOCB) = 32π + 64π = 96π
