What is the area of the shaded region

For this case we must find the area of the octagon and subtract the area from the square, in order to obtain the area of the shaded region.

So:

Where:

P: It is the perimeter

a: It is the apothem

We have to:

Substituting:

On the other hand:

Finally:

Option A

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
