Answer:
Option B. 
Step-by-step explanation:
we know that
The volume of a cone is equal to
Solve for the radius r
That means-----> isolate the variable r
Multiply by 3 both sides
Divide by 
both sides
square root both sides
The center is at (-1,-2) and radius of 5
Have a wonderful day! Here's a potato :3
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
