Question
Note: Figure not drawn to scale.
In the figure above, the circle has center A, and line : segment CB is tangent to the circle at point C. If AB = 1.0 and CB = 0.8, what is the length of the diameter of the circle?
The correct answer is: 6/5
AB2 = AC2 + BC2
12 = AC2 + 0.82
1 – 0.64 = AC2
0.36 = AC2
AC = 0.6
Diameter = 2 AC = 1.2
