Circumference Formula: C = πd

  • C is circumference
  • d is diameter

Step-by-step explanation:

*Note: The perimeter of a circle is the circumference.

Step 1: Define

Diameter d = 5.5 mi

Step 2: Find C

  1. Substitute [CF]:                    C = π(5.5 mi)
  2. Multiply:                                C = 5.5π mi
  3. Evaluate (~3.14):                   C ≈ 17.27 mi

Answer:

Perimeter of the circle is 2π(radius)

=2πr

=π(2r)

=π×Diameter

[tex](\pi \times 5.5 )\: miles = 3.14 \times 5.5 \\ = 17.27 \: miles[/tex]

17.27 miles is the right answer.
