A ring-shaped region is shown below.
Its inner radius is 6 m, and its outer radius is 9 m.
9 m
Find the area of the shaded region.
Use 3.14 for it. Do not round your answer.

Final answer is 5/6.

Step-by-step explanation:

Given that you roll a standard six sided number cube.

Now we need to find about what is the probability of rolling a prime number or a number greater than 3.

Total numbers in a six sided cube = 6 {1,2,3,4,5,6}

Total prime or numbers greater than 3 in a six sided cube = 5 {2,3,4,5,6}

Hence probability of rolling a prime number or a number greater than 3 = [favorable number of events] / [total possible events] = 5/6

Hence final answer is 5/6.
