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

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 = (22)/(7)`

`r = 3m`

substituting into the formula , we have

`C = 2 ((22)/(7))(3)`

`C = (132)/(7)`

`C = 18.85714285714`
`m`

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