| Satellites | |
| The radius of earth is 6440 Kilometer. There are many Satellites | |
| and Asteroids moving around the earth. If two Satellites create | |
| an angle with the center of earth, can you find out the distance | |
| between them? | |
| By distance we mean both the arc and chord | |
| distances. Both satellites are on the same orbit (However, please | |
| consider that they are revolving on a circular path rather than | |
| an elliptical path). | |
| Input | |
| The input file will contain one or more test cases. | |
| Each test case consists of one line containing two-integer s | |
| and a, and a string ‘min’ or ‘deg’. Here s is the distance of the | |
| satellite from the surface of the earth and a is the angle that the | |
| satellites make with the center of earth. It may be in minutes (′) or in degrees (◦). Remember that the | |
| same line will never contain minute and degree at a time. | |
| Output | |
| For each test case, print one line containing the required distances i.e. both arc distance and chord | |
| distance respectively between two satellites in Kilometer. The distance will be a floating-point value | |
| with six digits after decimal point. | |
