To find the circumference of the park and the fountain, use C = 2πr for the park and C = πd for the fountain.
To calculate the circumference of the park, you can use the formula C = 2πr, where r is the radius. For the park with a radius of 400 m, C = 2π(400) = 800π ≈ 2513.27 m.
For the fountain, with a diameter of 6 m, the circumference can be found using the formula C = πd, where d is the diameter. So, C = π(6) ≈ 18.85 m.
