LEAF - Leaf |
A leaf is inscribed in a square. Given the length of a side of the square. Find the area of the leaf.
A leaf is the intersection of two quarter circles drawn from two opposite ends of a square, with the radius being equal to the length of a side of the square.
Input
In the first line there will be an integer t (t ≤ 105) the number of testcases. Next t lines will contain a number a (0 ≤ a ≤ 106), the side length of the square.
Output
Print the area of the Leaf. Errors less than 10-6 will be ignored.
Example
Input: 2
1
2
Output: 0.5707963268
2.2831853072

The test files should be fixed now. I set this problem when I had no idea about floating point numbers. ☹️ |

After compiling with C++ (g++ 4.3.2), I got accepted. |

What is the point of telling us what PI is but not the shape of the leaf? |

getting wa can you check the code the code gives the ans for 1000000 as 570796326794.896606445 |

AC in one go. Use PI=acos(-1) and no unnecessary assumptions. Last edit: 2016-05-19 02:23:05 |

The problem as is can't stay visible. doubles have at most 15 or 16 significant digits correct. That means that a=1000000 and 6 decimal places after the decimal point can never be correct using doubles. So the problem must be hidden and moved out of classical |

Do "In the first line there will be an integer t" means there will also be other non integer things in first line? |
