Question

A dog is on a 5 ft leash staked to the ground. If he can rotate around the stake, forming a circle, what is the area of the grass he can cover? Use 3.14 for π.

Answer 1

78.5 ft²

Explanation:

In this situation, the dog's 5 ft leash is the radius of the circle that he forms.

So, the radius is 5.

Use the area formula, A =
`\pi`r². Plug in 5 as r, and 3.14 as
`\pi`

A =
`\pi`r²

A = (3.14)(5²)

A = (3.14)(25)

A = 78.5

So, the area of the grass he can cover is 78.5 ft²
