![12\pi \: {cm}^{2}](https://tex.z-dn.net/?f=12%5Cpi%20%5C%3A%20%20%7Bcm%7D%5E%7B2%7D%20)
EXPLANATION
We want to find the area of the shaded region.
We find the area of the smaller circle and subtract from the area of the larger circle.
Area of smaller circle is
![a = \pi \: \times 2^{2} = 4\pi](https://tex.z-dn.net/?f=a%20%3D%20%5Cpi%20%5C%3A%20%5Ctimes%20%20%202%5E%7B2%7D%20%20%3D%204%5Cpi)
Area of larger circle is
![A = \pi \: \times {4}^{2} = 16\pi](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20%5C%3A%20%20%20%5Ctimes%20%7B4%7D%5E%7B2%7D%20%20%3D%2016%5Cpi)
The area of the shaded region is:
![16\pi - 4\pi = 12\pi](https://tex.z-dn.net/?f=16%5Cpi%20-%204%5Cpi%20%3D%2012%5Cpi)
It leaves Chicago at 11:49 am and takes 2 hrs 26 min.
So in central time, that gets you to Denver at 2:15 PM.
Since mountain time is one hour behind central time, your answer would be 1:15 PM.
7x = 10
•Paula added 7 to 10, which was her mistake. To fix her mistake, she would have to divide by 7, instead of adding 7. The correct answer is 10/7.
