A. 6 centimeters
B. 12 centimeters
C. 18 centimeters
D. 3 centimeters
That's Correct!
It's Wrong!

It is given that:

CD = 6 centimeters

Observe that CD is a radius of the circle.

So, radius = 6 centimeters

And, AB is the diameter of the circle. So, let's find the diameter of the circle.

Now, we know that:

Diameter = 2 × Radius

Multiply the radius by 2 to find the diameter.

2 × 6 = 12

Diameter = 12 centimeters

So, the length of AB is 12 centimeters
