Circle Areas #2: The Basics

Geometry Level 3

In the diagram above, Circle O is circumscribed about Triangle ABC, where AB=44, AC=44, and BC=66. The area of Circle O can be expressed as aπb\frac { a\pi }{ b }, where a,ba,b are constants, are positive integers, and share no common factors greater than 1. What is a+ba+b?
