A 6 inch length cylindrical through hole is drilled through the center of sphere, what will be the remaining volume of sphere ?In this question only one data is given ie., hole length – 6″. In the question there is no mistake. Find the answer.

One Answer on this Question

1. volume of a sphere is 4/3 * pi * r^3
   by drilling a hole 6 inches long the volume of the sphere is
   not affected bcos the hole is a 1 dimension quantity..(say a
   straight line) n so it does not have any value w.r.t volume…
   hence the volume of the sphere does not change..
