Sorry this is hard to explain:
I have a quarter of a circle in a square and a smaller quarter of a circle in a square it's a bit like a path the measurements of the outside of the square are 7m.
I need to find out the area of the path.
Thanks in advance
All i have is that the outer sqaure is 7 and the path is 2m across
so for the outer circle is it pi x 7 squared / 4
and then pi x 5 squared / 4 for the inner circle.
do you take the two numbers from each other is that your area?
then how would you work out the length of the edges on the circle is this possible?
thanks for your help
I only now realized that "path" from post #1 is supposed to mean a part of a ring, or annulus.
Suppose the radius of the bigger sector is R and the radius of the smaller one is r. Then the area of the quarter ring is . You are saying that R - r = 2, but unfortunately, this is not enough to determine the ring area. You also need R + r, or, equivalently, R and r separately. The only information I get from the picture is that R < 7 and r < R. So there is not enough information to find the ring area.
