The radius of circle O is 24, and OC = 11. Find AB. Round to the nearest tenth, if necessary. The figure is not drawn to scale.

**Answer 1**

OB is a radius of the circle. Its length is 24. OC is given as 11.

These are the hypotenuse and one side of a right triangle.

The length of the remaining side (BC) is:

24^2 – 11^2

576 – 121 = 455

BC = 21.33

So AB is twice BC = 42.7
