An electronic dartboard has a diameter of 10 inches. the bull’s-eye has a radius of 1.5 inches. if a dart hits the board randomly, what is the chance it hits the bull’s-eye? check all that apply.
the dartboard area is roughly 78.54 square inches.
the dartboard area is roughly 314.16 square inches.
the bull’s-eye area is roughly 7.07 square inches.
the probability that a random dart strikes the bull’s-eye is roughly 0.09.
the probability that a random dart strikes the bull’s-eye is roughly 0.02.

Options

a); c); d)

Step-by-step explanation:

We calculate the area of the target using the formula of the area of a circle

Where r is the radius, which is equal to half the diameter.

Then the radius of the dartboard is 10 inches

Your area is:

We use the same formula to calculate the area of the porthole.

Where r = 1.5 in

The probability that a randomly launched dart hits the bull's eye is:

Finally the answer is:

- The dartboard area is roughly 78.54 square inches.

- The bull’s-eye area is roughly 7.07 square inches.

- The probability that a random dart strikes the bull’s-eye is roughly 0.09.
