Answer with Explanation:
Disc, is a three dimensional shape,made up of circles of different radii and is uncovered from top.Different from Bowl,which is quite deeper, do not extend far down from top.
So,to make a cone , you have to take three points on the surface of the disc such that it forms a triangular shape,and when you cut it,you will get a shape similar to cone.
So, it is a false statement, which asserts that, A cone is a solid made from a disc, any point on that disc, and all points between them.
