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

In researching his history report about the civil war, why is ariq most likely to use secondary data than primary data? secondary data provides a starting point to find primary data. secondary data is easier and less time consuming to find. secondary data is always more reliable and credible. secondary data eliminates the need for other research.

1. write a statement that declares a string variable named city. the variable should be initialized so it references an object with the string “san francisco”. a) assume that stringlength is an int variable. write a statement that stores the length of the string referenced by the city variable (declared in question1) in stringlength. b) assume that onechar is a char variable. write a statement that stores the first char- acter in the string referenced by the city variable (declared in question1) in onechar. c) assume that uppercity is a string reference variable. write a statement that stores the uppercase equivalent of the string referenced by the city variable (declared in question 1) in uppercity. d) assume that lowercity is a string reference variable. write a statement that stores the lowercase equivalent of the string referenced by the city variable (declared in question 1) in lowercity.
