Question

A puppy is tied to a leash in a back yard. 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?

Answer 1

So is it between 18 and 19 meters?

Answer 2

The approximate distance the puppy runs in one lap is approximately 18.85 meters. This is calculated by using the formula for the circumference of a circle, which is 2πr (where r is the radius of the circle). In this case, the radius is half of the length of the leash, which is 1.5 meters. Therefore, the circumference of the circle (the distance the puppy runs in one lap) is 2π(1.5) = 9.42 meters. Multiplying this by 2 gives us approximately 18.85 meters.

Answer 3

Yes, that is correct. The approximate distance the puppy runs in one lap is between 18 and 19 meters.
