[edit] Hints

Hint One
    Surely somebody must have looked at the diagram and realized that the triangle formed by points A, B, and C is a right triangle.

    That's sharp thinking and exactly right. However, are you sure there isn't a much easier way to find the answer?

Hint Two
    You don't need the Pythagorean theorem to answer this one. Something else in the diagram should be the exact same length as AC.

Hint Three
    Notice that diagonal line AC within the rectangle is the same size as the diagonal line BD.

    Have you also noticed that BD is also the same length as another part of this diagram?

[edit] When Failed

No, no, no!

Look at things again. You shouldn't have to do any difficult calculations to get to the answer.

[edit] When Completed

Righto!

Diagonal line AC is the exact same length as diagonal line BD. BD is the same length as the radius of the circle, so once you've figured that out, the only thing left to do is add five and five.

[edit] Solution

Line AC is 10 inches.

300 Picarats and 31 Hint Coins.
