Question

A tire is hung from a tree. The outside diameter is 34 inches and the inside

diameter is 14 inches. You throw a baseball toward the opening of the tire.
Your baseball is equally likely to hit any point on the tire or in the opening
of the tire. What is the probability that you will throw the baseball through
the opening in the tire?

Answer 1

Explanation:

Area of hole = pi r^2 = 49 pi

Entire area covered by tire = pi 17^2 = 289 pi

liklihood of 'hitting' the hole = 49 pi / 289 pi = 49/289
