Constraints

* 0 < r < 10000

Input

A real number r is given.

Output

Print the area and circumference of the circle in a line. Put a single space between them. The output should not contain an absolute error greater than 10-5.

Examples

Input

2


Output

12.566371 12.566371


Input

3


Output

28.274334 18.849556
x = raw_input()
r = float(x)
s = r * r * 3.14159265359
l = 2 * r * 3.14159265359
print "%.6f %.6f" % (s,l)
