CPM Homework Help : INT2 Problem 12-108

Circle, with center, c, has a horizontal diameter intersecting a chord on the right side of the circle. The segments around the point of intersection are labeled as follows: top, 4, right, 2, bottom, 3, left, unknown. Determine the area and circumference of circle $⊙C$ at right. Show all work.

Hint:

When two chords in a circle intersect, a proportional relationship between the lengths of the resulting segments occurs.
