Still giving out the thing :)
just answer its as simple as that and you get points :)

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

Assume you need to test a function named inorder. the function inorder receives three int arguments and returns true if and only if the arguments are in non-decreasing order: that is, the second argument is not < the first and the third is not < the second. write the definition of driver function testinorder whose job it is to determine whether inorder is correct. so testinorder returns true if inorder is correct and returns false otherwise. for the purposes of this exercise, assume inorder is an expensive function call, so call it as few times as possible!
