12-33.

Use all your circle relationships to solve for the variables in each of the diagrams below. 

  1. and intersect at .
    A circle with chords C D, and A B, which intersect at point labeled E, Line segments labeled as follows: E C, & E D, each have 1 tick mark, E B, is 8, & E A, is 18.

  1. The area of is sq. units
    Two secant lines, one going through the center of the circle meet externally. For the secant line going through the center, the distance from the point of intersection to the edge of the circle, is 4. For the second secant line, the distance from the point of intersection to the first edge of the circle is, k, and to the second edge is 8.

    Because the area is , that means the radius is , and the diameter is .
