Circle A and circle B are concentric. A chord of circle A that is tangent to circle B has a length that is twice the radius of circle B. What is the ratio of the area of circle A to the area circle B?
Circle B radius > Rb = 1
Circle A radius > Ra = ? Ra = sqrt [ (Rb)2 + (C/2)2 ] Ra = 2.236 u2
Chord length > C = 2
Area of A > A1 = ? A1 = (Ra)2 * pai A1 = 15.708 u2
Area of B > A2 = ? A2 = (Rb)2* pai A2 = 3.14159 u2
Ratio > A : B = ? A : B = A1 / A2 A : B = 5 : 1
