Use what you know about calculating area to find the geometric probabilities.
Label area calculations in units squared. For example, 24 in².
You will find each white and shaded area separately in each diagram. Then you will be asked to find the probability of hitting certain areas with a dart. All measurements are in centimeters. You must show your work or explain your answer to receive full credit.
Use pi (π) on your calculator, NOT a rounded 3.14.
