8.11 The student will analyze problem situations, including games of chance, board games, or grading scales using their knowledge of probability.

Questions

1) Move the slider to change the radius. How does the area change in relation to the change in radius size?

2) What is the area of the purple shaded region when the radius r =0? when r =1? when r =2? when r =3? when r =4? when r =5?

3) You are playing a carnival game. To win, you must land on the circle. What is the probability of winning when
r =0? r =1? r =2? r=3? r=4? r=5?
