Question

A fountain with a circular base is situated at the center of a circular basin. The base of the fountain is 5 ft in diameter. The basin is 10 ft in diameter and 3 ft high.The basin can hold ____ π cubic feet of water.

Answer 1

To find the answer, we use

$(\pi r^2_b-\pi r^2_f)\cdot3=(\pi(5)^2-\pi(2,5)^2)\cdot3=56.25\pi ft^3^{}$

pi*rb^2 represents the volume of the basin.

pi*rf^2 represents the volume of the fountain.

the height is 3.
