Problem type

Simon got a new drill recently. Everyone knows that a drill is shaped like a right circular cone. Simon knows his drill has radius $r$ ~r~ and height $h$ ~h~. But now he wants to calculate the volume. Write a program to help Simon!

Input Specification

The first line of input will have an integer $r$ ~r~ $(1 \le r \le 100)$ ~(1 \le r \le 100)~.

The second line of input will have an integer $h$ ~h~ $(1 \le h \le 100)$ ~(1 \le h \le 100)~.

Output Specification

The first line of output should have the volume of Simon's drill. The output will be accepted if it's within an absolute or relative error of $10^{-2}$ ~10^{-2}~.

Sample Input

3
5

Sample Output

47.12

Hint

$V$ ~V~ is the volume of the right circular cone with radius $r$ ~r~ and height $h$ ~h~.

$V=\dfrac{\pi r^2h}{3}$ ~V=\dfrac{\pi r^2h}{3}~

This evaluates to wrong if you use text to prompt the User. The input() function has to be blank. (on python 3)

The identical checker is being used. Follow the standard convention of having all lines terminate in a \n character, with no trailing whitespace.

PI=3.141592653589793 print('enter radius=') radius=int(input()) print('enter height=') height=int(input()) volume=(PIradius**2height)/3 print(volume)
