**Reiny**, Saturday, April 17, 2010 at 7:16pmYou don't need Calculus to do this.

The outer circle has centre at (0,0) and has radius 8

The other circle has centre (4,0) and radius 4, so the touch at (8,0)

The big circle has area 64π, so the area in the first quad is 16π

The smaller circle has area 16π and half of it lies in quad I, so the area in there is 8π

So the area between the big circle and the little circle in quad I = 16π-8π = 8π
