Consider a logical address space of 1024 pages of 4,096 bytes each, mapped onto a physical memory of 8192 frames. For each question in the left column, match it to the correct response in the right column. - The number bits required in the logical address. - The number bits required in the physical address. - The number bits required in offset. - The number bits required to represent the page number. - The number bits required to represent the frame number. a. 22 b. 30 c. 12 d. 10 e. 25 f. 8 g. 20 h. 13

Pp 4.1 design and implement a class called sphere that contains instance data that represents the sphere’s diameter. define the sphere constructor to accept and initialize the diameter and include getter and setter methods for the diameter. include methods that calculate and return the volume and surface area of the sphere (see pp 3.5 for the formulas). include a tostring method that returns a one-line description of the sphere. create a driver class called multisphere, whose main method instantiates and updates several sphere objects.
