Who stole my pizza?
After Joe bought a perfectly circular pizza, a large chunk of it was sliced off and stolen by a hungry thief, who was kind enough to leave Joe a dome-like piece similar to the figure above.
If AB = 3 in., BC = 7 in., and CA = 6 in. respectively, what is the area of the original whole pizza in square-inch? (Round the answer up to the nearest integer.)
The answer is 39.
