The diameter of a circle is the same length as the side of a square . The perimeter of the square is 16 cm . Find the diameter of the circle . Then find the circumference of the circle in terms pie?
perimeter of a square = 4*side by substituting 16=4*side dividing by 4 side=4 since diameter=side then the circumference =d*pi therefore=4*pi is the circumference
