Answer:
Top: 18.85
Middle: 28.27
Bottom: 37.7
Step-by-step explanation:
Equation to find circumference: 2(pi)r
The top circle has a diameter of 6; thus, the radius would be 3. Plugging 3 into the equation would get you 18.85
The middle circle has a diameter of 9; thus, the radius would be 4.5. Plugging 4.5 into the equation would get you 28.27
The bottom circle has a diameter of 12; thus, the radius would be 6. Plugging 6 into the equation would get you 37.7
Hope this helps!
