) Consider the ambiguous CFG problem: given a context free grammar, does there exist a string that can be generated by two different parse trees. Show that this problem is undecidable by reducing the post correspondence problem to it. The post correspondence problem is the following: given two sequences of strings a1, ..., an and b1, ..., bn, is there a sequence of indices i1, ..., im (with possibly repeats, and whose total length may be much bigger than n) such that ai1 ai2 ...aim = bi1 bi2 ...bim?

Write a program that will compute the volume of ice cream served in a cone. as you can see in the diagram below, the ice cream is served as a hemisphere of frozen deliciousness on top of a cone, which is also packed with frozen deliciousness. thus, the total volume of ice cream sold is the volume of the hemisphere plus the volume of the cone. the example shows an ice cream cone in which the hemisphere and cone have a radius of 10 inches and the cone has a height of 15 inches. your program must instead prompt for these two values, which are taken from the keyboard as integers: • the hemisphere/cone radius in inches, and
