Exercise B: (Area of a Circle)

This program calculates the area of a circle. The formula for the area of a circle is PI times the radius squared. PI = 3.14159

• Ask the user to enter the radius of a circle.
• Calculate the area of the circle and display the number up to 2 decimal points.

(To set the decimal point include, #include )

• You must declare PI as named constant.
• You must use math function pow() to square the radius. Do not write radius * radius.

(You need to include, #include for pow function.)

Test Case:

Run your program two times. First time enter the value of the radius = 12. Second-time radius = 5.23.

Here is the expected output. Your code should be able to handle any number entered by the user. I am just giving you these 2 numbers to check the accuracy of your code.

Exercise C: (Simple Math)

Write a program that produces the following output (make sure you pay attention to spaces, lines, and upper- and lower-case). Use only variables of int type.

Your output must match with my output. If there is space between 2 lines, your output must show that space.
