A circular playground has 2 parellel roads running through it. Their lengths are 112m and 50m. The perpendicular distance between these roads is 92m.
Find the diameter of the playground.

re: First Steps by Cheradenine)
When it comes to the final "plug in the numbers" steps, I have all too often found that in my rush to finish I wound up doing something dumb like adding 2 = 2 and getting 5.
So when r and D did not come out as "elegantly" as I'd expected, I assumed I'd done it again. That's why I was planning to tackle it fresh after a good night's sleep.
The fact that you, too got the "inelegant" answers had me double-checking that the squares of 25, 56, and 92 were correctly given as 625, 3136, and 8464.
