A round swimming pool has a diameter of 15 feet and is 6 feet tall. How much water will the pool hold?

Sagot :

Use the formula for Volume of Cylinder: 
V = π r² h


where:
π = 3.14
r (radius) = 1/2 (diameter), if diameter is given
                = 1/2 (15 feet)
                = 7.5 feet
height = 6 feet

V = (3.14) (7.5 ft)² (6 ft)
    = (3.14) (56.25 ft²) (6 ft)
    = 1,059.75 ft³

The pool can hold 1,059.75 cubic feet of water.
First know the equation needed then solve:
V = πr²h
V=(3.14)(15÷2)²(6)
V=(3.14)(56.25)(6)
V=(176.625)(6)
V=1059.75 ft.³
