Question 807490: In the figure below, the circle centered at
B
is internally tangent to the circle centered
at
A
. The smaller circle passes through the center of the larger circle and the length
of
AB
is 5 units. If the smaller circle is cut out of the larger circle, how much of the
area, in square units, of the larger circle will remain?

Since the small circle is internally tangent to the larger one, the distance from B to the the larger circle has to be equal to the distance between the two circle centers. Hence the radius of B is 5 and the radius of A is 10.
Calculate:
\ -\ \pi(5^2))
