An above ground swimming pool in the shape of a cylinder has a diameter of 21 feet and a height of 3.5 feet. If the pool is filled with water up to 9 inches from the top of the pool, what is the volume (to the nearest cubic foot) of water in the pool?

Respuesta :

Answer:

952 cubic feet

Step-by-step explanation:

The diameter is 21, so the radius is 10.5. The area of a circle is πr^2, so 10.5^2π, or 110.25π. The pool is filled 9 inches from the top, so it is 3.5 feet - 9 inches high, 9 inches is 0.75 feet, so 2.75 feet filled. Now multiply 110.25π by 2.75 to get 303.1875π and then 952.4916, closer to 952 cubic feet.
