I'm not even going to try to guess whether you meant A(2,5) and B(10,5) or A(92,5) and B(910,5). If you are too lazy to make sure that your problem is typed accurately, then I am too lazy to do the work you expect me to do.
Use the distance formula to calculate the measure of the diameter using the coordinates of whatever the endpoints really are:
^2 + (y_1 - y_2)^2})
Where ) and ) are the coordinates of the given points.
Once you have the measure of the diameter, divide by 2 to get the measure of the radius, then use:
 to calculate the area.
By the way, "pie" is a dessert item, generally circular and generally having a flaky pastry crust, and frequently having some sort of fruit filling. "pi" is the lower case Greek alphabet character generally used to denote the ratio between the circumference and diameter of a circle. You should leave your answer to this question expressed in terms of "pi" rather than "pie" -- unless the circle mentioned in the question actually represents your dessert and you specify the flavor of the filling.
