Garrett throws a dart at a circular dartboard

Garrett throws a dart at a circular dart board. The dart board has a radius of 18 inches, and the bull’s eye in the center of the dart board has a radius of 4 inches. What is the probability that a dart thrown at random within the dartboard will hit the bull’s eye? Round your answer to the nearest tenth, if necessary.
A

To find the answer, we have to divide the area of a circle for bull’s eye by the area of the circle for dart board.

The area of a circle formula is:

A = π * r2

Dart board radius = 18

Bull’s eye radius = 4

Probability = A2/A1 = (π * 42) / (π * 182) = 4.94%
