To determine the length of a circle that is 3 feet wide, we need to first understand the concept of diameter and circumference. The diameter is the width of the circle, which in this case is 3 feet.
The formula for finding the circumference (the distance around the circle) is given by:
C = π × d
Where C is the circumference and d is the diameter. Here, we can substitute our diameter:
C = π × 3
Using the value of π (pi) as approximately 3.14, we can calculate:
C ≈ 3.14 × 3
C ≈ 9.42 feet
Therefore, the length of a circle that is 3 feet wide (i.e., with a diameter of 3 feet) is approximately 9.42 feet.
