Answer:

area of the tile used for the bottom of the swimming pool is 1256 sq.feet

Step-by-step explanation:

given, there is a circular swimming pool with a diameter of 40 feet

radius of the pool = 20 feet

to find: area of tiles used

area of circle = πr²

                = 3.14× 20²

                = 3.14× 400

                = 1256 square feet

therefore, area of the tile used for the bottom of the swimming pool is 1256 sq.feet
