Question

A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary.

Answer 1

300pi square feet

Explanation:

the dog can move inside of the 3/4 of a circle

the area of a circle is the radius squared times pi

20*20*pi=400pi

Since the house takes up 1/4 of the circle the dog is left with 3/4

400pi*3/4=300pi
