A circle of area 25 pi is graphed in the coordinate plane. If its center has coordinates (8,0), which of the following points MUST lie on the circumference of the circle?
a. (0,0)
b. (0,5)
c. (16,0)
d. (3,0)
e. (0,8)
please answer and explain

radius is 5, so since (3,0) is 5 units to the left of (8,0), that's our point.
(d)
