A circle with radius "x" has area $\pi x^2$, a circle with radius "y" has area $\pi y^2$ and, since y> x, the area between them is $\pi y^2- \pi x^2= \pi(y^2- x^2)$. Concentric circle can be defined, in geometry, as two or more objects that have the same center or axis but different sizes. Step-by-step explanation: If the circle has a center at (8,9), the equation for this circle is: All concentric circles have the same center, so their equations need to have the same left side of the equation above.
