Two circles, both with a radius of 10, are tangent to each other. A tangent is drawn from the center of one circle, to the other circle. To the nearest interger, what is the area of the gray region?

Use Pythagoras again to find DC2 ( it is 6 * sqrt r) and C3B ( it is sqrt(-4r^2+52r)).
Since a rectangle has opposite sides equal:
DC2=C3A + C3B
Sub in the values we had before for these lengths to get:
2 * sqrt r = sqrt(-4r^2+52r)
Square that to get
4r = -4r^2 + 52r 4r^2 - 48r = 0 4r(r-12)=0
