Question from cey, a student: the diameter of the larger circle is 20cm, and the smaller 10cm. what is the shaded area?? how do i solve that help please |
Hi Cey,
I am assuming that the shaded area is as follows:
If you look at the diagram, it looks like a circle with a hole in the middle. If we "remove" the area of the small circle from the area of the large circle we will create that hole. In other words, to find the shaded area subtract the area of the smaller circle from the area of the larger area.
