Find the diameter

It sometimes gets the picture wrong but, that can be fixed with the problem edit system, this without a doubt would be the first thing I think of when my friend asks if I know any good calculators to help with simple or extremely complicated math.

Thanks a lot for developers, it has some problems but overall it is great for my homework I can take a picture of what I can not salve and it will give me the right answer and that is why I like this app so much.

But after all, amazing work! Thanks for creating this app, you are the best! (It also helps me with my studies, to understand things better etc. This app is great for students who don't have time to do homework. Often I try not too read to far into the solution just using the first few steps to get me going on a problem.
