1. Calculate the sum and the average of three scores that will be input by the user. Outputs will be all inputs and calculated data.

2. Using the value of radius, calculate the area and the circumference of a circle. Output will be all inputs and calculated data. Note: area is pi * r^2 and circumference is 2 * pi * r ( represents pi which is approximately 3.14159 and r represents radius).

3. Using the number of ounces read in as input, calculate the number of pounds and ounces left over. For example:

Use case 1: User enters 17 ounces

Output: 1 lbs 1 ounce left over

Use case 2: User enter 19 ounces

Output: 1 lbs 3 ounces left over

You are not allowed to use modulus. You should only use the four basic arithmetic operators.
