Question 542473: a circle with a 2 cm diameter is drawn inside a circle with a 6 cm radius. what is the area between the circles? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! it's the area of the larger circle minus the area of the smaller circle.
the area of a circle is equal to pi * r^2
the area of the smaller circle is equal to pi * 2^2 = pi * 4
the area of the larger circle is equal to pi * 6^2 = pi * 36
the area between the circles is equal to pi * 36 minus pi * 4 = pi * 32.
that's the area of the larger circle that does not include the area of the smaller circle within it.
