The three circles C1, C2 and C3 have their centers O1, O2 and O3 on the line L and are all tangent at the same point. If the diameter of the largest circle is 20 units, what is the ratio of the area of the largest circle to the area of the smallest circle?

ー The ratio of A to B is given by :

[tex]A / B = π \: (10)² \: / \: π \: (2.5)²[/tex]

[tex]= (10)² \: / \: (2.5)²[/tex]

[tex]= (10 \: / \: 2.5)² = 4² = 16[/tex]
