Find the exact perimeter of the shaded region! 10 points !

1 answer:

4 0

I believe the answer is 60.75pi, calculated as follows:

Area of Circle: (9 * 9) * pi = 81pi

Area of Shaded Area = (90 / 360) * 81p = 20.25pi

81pi - 20.25pi = 60.75pi

The easy way is to count outcomes. Of the 36 equally probable outcomes, 10 are less than or equal to 5, so the probability is 10/36 = 5/18.
