The area of the entire dart board can be calculated using the formula for the area of a circle: A = πr^2
A = π(18)^2
A = π(324)
A = 1017.88 square inches
The area of the bulls eye can be calculated using the same formula: A = πr^2
A = π(4)^2
A = π(16)
A = 50.27 square inches
Therefore, the probability of hitting the bulls eye is the ratio of the area of the bulls eye to the area of the entire dart board:
P = (50.27 / 1017.88) = 0.0494
Rounded to the nearest tenth, the probability is 0.1 or 10%.
