Please see image for Question, copying and pasting the format is hard.    An agronomist want to take soil sample from a circular patch of ground with radius 9 meters. Consider the center of the circle to be the point (0,0) and assume the agronomist randomly selects a point for the sample. Let X represent the x coordinate and Y represent the y coordinate of the point chosen, relative to the center. So it is true that (SEE IMAGE FOR NUMBERS)
