Design the instruction formats for the following instruction set using an expanding opcode. The size of all instructions is 32 bits, all register numbers are 4 bits, memory addresses are 20 bits, and the displacement field is 16 bits. For each category of instructions, show the instruction format, what fields it has, and the number of bits in each field. Also show the range of values for the opcode for each instruction category. • 15 instructions with two register numbers and one memory address
• 15 instructions with one register number and one memory address
• 60 instructions with one register number and one displacement
• 15 instructions with one displacement

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
