Suppose that all of the points on the circular dartboard shown are equally likely to be hit by a dart. if the radius of the red center circle is 2 in, and the radius of the entire dartboard is 6 in. what is the probability of throwing a dart and hitting the white part of the board? round your answer to the nearest whole number.

Option (d) i.e. 89%

Step-by-step explanation:

Area of a circle =

Now, area of inner red circle (radius = 2 in)

=

And, area of the dartboard (radius = 6 in)

=

⇒ The area of white part in the dartboard = Area of entire dartboard - inner red circle area = 36π - 4π = 32π

Now, Probability =

=

=

=

= 88.88% ≈ 89%

3.76%
