The image is not attached with, but by reading the question it is obvious that the blue region lies inside the larger square and outside the smaller square. That is the region between the two squares is the blue region.
We know the dimensions of both squares, using which we can find the area of both squares. Subtracting the area of smaller square from larger one, we can find the area of blue square and further we can find the said probability.
Area of larger square = 8 x 8 = 64 in²
Area of smaller square = 2 x 2 = 4 in²
Area of blue region = 64 - 4 = 60 in²
The probability that a randomly chosen point lies within the blue region = Area of blue region/Total area available
Therefore, the probability that a point chosen at random is in the blue region = 60/64 = 0.9375
Answer:
A) But if anyone thinks this they should go back to preschool
Step-by-step explanation:
On any other value of x you would take the numerators and denominators and multiply them across:

But, this literally does not make since considering the fact that you cannot divide any value by zero. Try it, it won't work. If we plug these into a trusty dusty calculator, we get this:

0*DOMAINERROR= You can't do it.
There are other reasons why you can't divide by zero, I would suggest looking them up on YT and learning about them.
I would answer A, but the person who wrote this question just wasn't focusing when they wrote the question.
Surface Area = 2πr² + 2πrh
Surface Area = 2π(7)² + 2π(7)(15) = 308π in²²
Answer: 308π in²
