Exercise

Write a Go program that accepts the radius of a circle as input, and returns the diameter, circumference, and area.

This program will require use of math.Pi in conjunction with math.Pow and multiplication operations.

Formulas

• D = radius * 2
• C = 2*π*r
• A = π*r²

Hint

How to read the input? You can figure it out by looking at the fmt package documentation.
