Mother's Kitchen, a canning company

Description

Mother's Kitchen, a canning company, wants to package a ready-to-eat spaghetti mix containing three different cylindrical cans: one of spaghetti sauce, one of grated cheese, and one of meatballs. Mother's needs to calculate the base areas, total surface areas, and volumes of the three different cans. It would also like to know, per package, the total base area, surface area, and volume.

The program to calculate this information uses these formulas and data:
base area = πr2.
volume = base area × height = πr2h.
surface area = 2 base areas + side area = 2πr2 + 2πrh.

Method:
  1. Enter an r value into the calculator and save it for other calculations. Calculate the base area (πr2), store it for later use, and add the basearea to a register which will hold the sum of all base areas.
  2. Enter h and calculate the volume πr2h). Add it to a register to hold the sum of all volumes.
  3. Recall r. Divide the volume by r and multiply by 2 to yield the side area. Recall the base area, multiply by 2, and add to the side area to yield the surface areas. Sum the surface areas in a register.
