This is basically how they got the correct answer.

First they used the area formula:


\pi * {r}^(2)

So for you that would be:


\pi * {9.8}^(2)

Which equals

301.7

Since there's a hole in the circle we do the area of a square which is base times height.

Which is 3 x 3 = 9 for your problem

Then we subtract

301.7 - 9 = 292.7 !

Which is almost exactly 292.57 since there is a margin
