From your post, I don't know and can not know what the shaded region is.

I only can guess, which is not a good style in doing Math.

By the way, the tongue is given to you to express your thoughts;
and more concretely, in this case to describe by your own words what the shaded region is.

Ok, I will assume that the shaded region is the segment of the circle with the central angle of 45°.

Then this sector area is      of the circle area.

So, you calculate the circle area   A =   (is this formula familiar to you ?)
and then take      of it as your answer.

In terms of   , the answer is     = = .

Solved.

Is everything clear to you from my explanation ?
