Question 876804: Hi,
The area of a circle of radius r is given by the formula A=πr^2. Use this fact to find the area for the shaded area in the figure below.
(The figure is a circle, with radius r, with another shaded circle surrounding it. The shaded part has a width marked 'w'.)
The answer given is A=2πrw + πw^2. Can you please explain how this is done.
Thanks.
