Circle

Time: 1 s · Memory: 256 MB

Statement

You are given the radius $r$ of a circle. Find the circumference $L = 2\pi r$ and the area $S = \pi r^2$ .

A single integer $r$ ( $1 \le r \le 1000$ ).

A single line with two numbers: first $L$ , then $S$ , each with exactly 2 digits after the decimal point.

Input

Output

6.28 3.14

Input

Output

62.83 314.16

Use the language's built-in constant for $\pi$ : Python — math.pi, C++ — M_PI (<cmath>), Go — math.Pi. Writing $3.14$ gives a wrong answer.

Use double (float64 in Go), not float: float is not precise enough to keep $\pi \cdot 1000^2$ correct to 2 digits.
