Hi,

Please see the file attached for explanation to each problem. Thanks.

1.

The tank capacity is simply the area of the cross section (a circle) multiplied by the tank height. The area of a circle is πD2/4 where D is the diameter.

Tank capacity = Volume of tank = A x h = πD2/4 x h

= π(250 feet)2/4 x 30 feet

=1.473 x 106 cubic feet

2.

Regardless of the amount of liquid in the tank, tank capacity should remain the same. Converting tank capacity to gallons (1 cubic ...

#### Solution Summary

The expert finds the capacity of a cylindrical tank that is 250 feet in diameter and 30 feet high.
