Meg pounded a stake into the ground. When she
attached a leash to both the stake and her dog’s collar,
the dog could reach 9 feet from the stake in any direction.
Using 3.14 for π, what is the approximate area of
the lawn, in square feet, the dog could reach from the
stake?

Respuesta :

The dog is able to run around in a circle with a radius of9 ft.

The area of a circle is A = pi r^2

A = (3.14) (9)^2
A= (3.14)(81)
A= 254.34 sq ft
