Circle Metrics Computation

Given the radius r of a circle, compute its diameter, circumference, and area.

Formulas used:

• \(\text{Diameter} = 2r\)
• \(\text{Circumference} = 2\times3.14159\times r\)
• \(\text{Area} = 3.14159\times r^2\)

Output each result with exactly 4 digits after the decimal point.

inputFormat

The input consists of a single real number representing the radius r of the circle.

outputFormat

Output three numbers: the diameter, circumference, and area of the circle, each rounded to 4 decimal places, separated by spaces.
