Find the Measure of the diameter of the circle. justify your answer...this is the question i have and they gave no picture with it...and i have no idea how to do it..even if ur not sure exactly how but you have some idea on how to solve it...itll be appreciated..thanks =]

Answer: isn't the diameter 8? because if P is the point of tangecy, it means it's on the edge, and four cm away from the center (which would make 4 the radius)..so eight is the diam.
