The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle.
Given that the radius of the trail is 45 yards, we can substitute this value into the formula:
C = 2 x π x 45 = 90π
Therefore, the circumference of the walking trail is approximately 282.74 yards.
