Answer:

2πr cm

Step-by-step explanation:

The circumference of a circle of radius r is ...

C = 2πr

For a radius of (r cm), the circumference is ...

A = 2π(r cm) = 2πr cm

For a radius of (2r cm), the circumference is ...

B = 2π(2r cm) = 4πr cm

Then the difference between the circumferences is ...

B -A = (4πr cm) -(2πr cm) = 2πr cm . . . . difference in circumference
