"joyce is decorating her store window for a going-out-of-business sale. she wants to design some art that looks like the diagram shown below. She will paint the shaded portion. How many square meters will she need to paint?"
We can help you when we see the diagram "below".
the answer to this question is very simple, i had the exact same question last year.
1) divide the circle into two, an upper part and a bottom .
2) now you have yourself 3 cirlces (draw them in)
3) find the areas of each of them and subtract it from the whole area of the entire circle.
4) now you have it! the answer is right there.
( when i handed this in, the teacher was suprised, i did a great job! an di got 100 percent on this)
