A puppy is tied to a leash in a backyard. His leash is 3 meters long,and he runs around in circles pulling the leash as far as it can go. What is the approximate distance the puppy runs in one lap?
The puppy runs around in a circle with a diameter of 3 meters (the length of the leash). To calculate the approximate distance the puppy runs in one lap (circumference), we use the formula:
Circumference = π x diameter
Circumference = π x 3 meters
Circumference ≈ 9.42 meters
Therefore, the puppy runs approximately 9.42 meters in one lap.
