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

its 9 meters and 20

Answer 2

Answer: between 18 and 19 meters

Step-by-step explanation:

The approximate distance the puppy runs is just simply the circumference of the circle.

The formula for calculating the circumference of a circle is given as :

C = $2\pi r$

$\pi = \frac{22}{7}$

$r = 3m$

substituting into the formula , we have

$C = 2 (\frac{22}{7})(3)$

$C = \frac{132}{7}$

$C = 18.85714285714$$m$

Therefore : The puppy runs between 18m and 19m in one lap
