A dart hits each dartboard below at random. What is the probability that the dart will land in the darkly shaded area? Homework Help ✎
First find the total area of the dartboard. A = r2?
Subtract the area of the lighter, smaller circle from the total area of the whole circle.
16π − 4π = 12π
Divide the difference between the areas of the dartboardand the small circle by the area of the dartboard.
Use the same method from part (a).
