Alice wants to build a deck around her circular pool that has a width of 4 feet. If the diameter of the pool is 12 feet, find the area of the deck and pool

Answer 1

If we drew a straight line theough the center of the pool touching the outside of the path on both ends, we'd add 4 feet on one end aaaaand 4 feet on the other. The radius is half the diameter.

A = πr²

A = π(10²)

A = 314 ft²
