The sum of three consecutive odd numbers is 57. which of the following numbers is the largest number in the series?

The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?
