Question

If the dog is given a 3-foot leash centered at the black dot, how many square feet is the area that he can reach? (Use 3.14 for pi)

A) 9π square feet
B) 28.26 square feet
C) 18.84 square feet
D) 42.78 square feet

Answer 1

The area that the dog can reach is approximately 7.065 square feet.

Step-by-step explanation:

To find the area that the dog can reach, we can use the formula for the area of a circle, which is A = πr². In this case, the radius of the circle is half of the length of the leash, so the radius is 1.5 feet. Plugging this value into the formula, we get:

A = 3.14 * (1.5)² = 3.14 * 2.25 = 7.065 square feet.

Therefore, the area that the dog can reach is approximately 7.065 square feet.
