Answer:
Explanation:
Figure 1
Total area = Area of square = 12 * 12 =144
Area of Shaded region =
Area of Square – Area of circle =
144 - pi r^2 = 144 – π 6*6=144-36π = 30.96
(Here the value \pi of is 3.14)
Probability = Area of Shaded region/Total area = 30.96/144=0.215
Rounded to the nearest 10th the answer is 21.5%
Area of circle = pi{10}^2=100 \pi=314
Area of arc AB = Area of quarter circle – Area of triangle OAB
=( pi{10}^2\ *1/4)-1/2 * 10*10 = 25pi – 50 = 28.5
Probability = Area of arc/Area of circle = 28.5/314 = 0.090
Rounded to nearest 10th the answer is 9%
