Q:
Consider two circles, a larger one and a smaller one. .if the larger one has a radius that is 3 feet larger than that of the smaller circle and the ratio of the circumstances is 2:1, what are the radii of the two circles?
---------------------------------------------------------------------
A:
Let x = radius of smaller circle
so x + 3 = radius of larger circle
2%2Api%2A%28x%2B3%29%2F%282%2Api%2Ax%29 = 2
%28x%2B3%29%2Fx = 2
x + 3 = 2x
x = 3
so x + 3 = 6
The radii of the circles are 3 ft and 6 ft.
