The 19th century German mathematician Hermann Minkowski investigated a non-Euclidian geometry, called the taxicab geometry. In taxicab geometry the distance between two points T1(x1, y1) and T2(x2, y2) is defined as:### Input

The first and only line of input will contain the radius *R*, an integer smaller than or equal to 10000.### Output

On the first line you should output the area of a circle with radius *R* in normal (Euclidian) geometry.
On the second line you should output the area of a circle with radius *R* in taxicab geometry.### Sample Input #1

### Sample Output #1

### Sample Input #2

### Sample Output #2

### Sample Output #3

### Sample Output #3

D(T1,T2) = |x1 - x2| + |y1 - y2|

All other definitions are the same as in Euclidian geometry, including that of a circle:

A **circle** is the set of all points in a plane at a fixed distance (the radius) from a fixed point (the centre of the circle).

We are interested in the difference of the areas of two circles with radius *R*, one of which is in normal (Euclidian) geometry, and the other in taxicab geometry. The burden of solving this difficult problem has fallen onto you.

Note: Outputs within +/-0.0001 of the official solution will be accepted.
