Garrett thros a dart at a circular dart board. the dart board has a radius of 16 inches, and the bull's eye in the center of the dart board has a radius of 6 inches. What is the probability that a dart thrown at random within the dartboard will hit the bull's eye?

Answer 1

area bulls eye = pi (6^2)
total area = pi (16)^2

6^2/16^2 = 2^2*3^2 /2^8 = 9/2^6 = 9/64
= .140625
