Description
Write a program that given the radius, computes the area and circumference of a circle,
as well as the volume of a sphere that is built with that circle.
a) Greet the user to the circle calculator. (5 points)
b) Also ask them to input the radius of the circle, and the name of that circle (one character
only). (15 points)
c) Compute the area, circumference and volume of the sphere made with that circle. The
equations are as follows (30 points):
𝐶 = 2𝜋𝑟
𝐴 = 𝜋𝑟
2
𝑉 =
4
3
𝜋𝑟
3
d) Display the results back to the user using the printf function. Mention the name of
that circle in the output. The result should be displayed with 3 decimal places and fully
identifiable (20 points).
Note1: All constants must be defined as a constant macro.
Note2: Your calculations must be very accurate. Double check the output of your program
for different inputs, and also using your personal calculator to make sure they match.
Note3: Make sure you have a visually appealing output. Use the escape sequences for
this purpose.
