Answer 1

Answer:

Step-by-step explanation:

According to the given condition, <br> Circumference of circle = Circumference of first circle + Circumference of second circle

Answer 2

Answer:

Step-by-step explanation:

Circumference of the bigger circle=Circumference of 1st circle + Circumference of 2nd circle

Circumference of the circle=2πR + 2πr

Circumference of the circle=2π(R+r)
