Step-by-step explanation:
The common formula for figuring out a probability is the desired outcome/total number of outcomes.
The desired number of outcomes would be the area of the circle, which is:
pi(radius)^2=A
3.14(7cm)^2 = 153.86
The total number of outcomes equals the area of the rectangle, which is:
A= length x width
A = 28*22
A = 616cm
Thus, the probability of the ball hitting the circle is:
153.86/616
