First you have to find the area of the full circle.
Area of circle:
A = pi radius^2.
A = 4 x 4
A = 16 pi squared
Area of rectangle:
3 x 3 = 9 cm

Answer: 0.2119
Step-by-step explanation:
We assume that the random variable X is normally distributed.
Given : Population mean : 
Standard deviation :

Then, z-score corresponds to 116

By using the standard normal distribution table for z , we have


Hence, the required probability = 0.2119
