The radius of ⨀B is 4 centimeters and the circumference of ⨀A is 20π centimeters. Find CD

24

Step-by-step explanation:

If we're using CD as simply numbers and not references to their designated circles we can use the difference between A and B as a pattern

The circumference is 2 multiplied by pi by the radius. This would mean that A has a radius of 10.

The difference between A and B is 2 so we can assume that C is 6 and D is 4. 4*6=24.
