The number of square units in the area of circle P is equal to the number of units in the circumference of circle P. Assuming that the diameter of the circle must be greater than P, what is the radius of circle P ?
b. 2 pi
d. 4 pi
e. cannot be determined from the information given
please answer and explain
pi r^2 = 2pi r
divide by pi*r to get
Since P is a circle, it makes no sense to say the "diameter must be greater than P".
