Four circular parks of different sizes are to be surrounded with fence. Park 1 has half the diameter of Park 2, one third the diameter of Park 3, and one fourth the diameter of Park 4. If one bundle of fence exactly surrounds park 2, how many bundles of fence will be used in this project?​

Respuesta :

Answer: 5 bundles are needed

Step-by-step explanation: Say that the length of the bundles are 10          Then the amount needed for park 2 would be 10pi. Then you would need 5pi for park 1. Then 15pi would be needed for park 3, and 20pi would be needed for park 4. Adding it all up, it would be 50pi. Dividing 50pi by the original bundle length 10pi, we get 5 as our length.
