Henry needs to give informal proof of the formula for the circumference of a circle.
He first constructs a circle, with center O, and labels a point on the circle as P.
He draws a radius from O to P.
He then uses point P as the center to construct a new circle.
He draws two line segments, each formed by joining point O with the points of intersection of the two circles.
Which of these is a plausible next step in Henry's proof process?
Construct another circle with a doubled radius.
Construct a rectangle that circumscribes the original circle.
Construct an octagon that circumscribes the original circle.
Construct a hexagon inscribed in the original circle
