Points A (-1, 2) and B (3, 2)are the endpoints of a diameter of a circle graphed in a coordinate plane. How many square units are in the area of the circle? Express your answer in terms of $pi$.
+428 we use the distant formula to found out that the diameter is 4 then we divide it by 2 and found out that the radius is 2 the area of this circle is 4\( \pi\)
