The formula to find the circumference of a circle is C = 2πr, where C represents the circumference, and r represents the radius.
In this case, the radius is 2.5 feet, so we can substitute that value into the formula:
C = 2π(2.5)
C = 5π
Using the approximation of π as 3.14, we can estimate the circumference to the tenths place:
C ≈ 5(3.14)
C ≈ 15.7 feet
Therefore, the circumference of a circle with a radius of 2.5 feet is approximately 15.7 feet.
