The amount of liquid a cylinder holds is its volume, and to find the volume of a cylinder, the equation of a cylinder is V=pi(r squared)h. Basically, the radius squared times the height, times pi.

First, convert the height to inches, so 2 feet is 24 inches. Then, multiply 6.5 by 6.5 to get r squared, which is 42.25. Then, multiply that by the height, which is 24. This makes is 1,014 pi. You could leave your answer as that, or multiply 1,014 by pi (approximtely 3.14). This is around 3,183.96.

so, first of all, you have to find the area of the base, so find the area of a circle that would have a radius of 6.5

the formula for area of a circle is (pi)(r)^2 (pi x radius x Radius)

so, plug in the radius, 6.5

6.5 squared is….42.25

42.25 times pi (3.14)=…132.665

so the area of your base is 132.665. now multiply this number by the height of the cylinder, but DONT BE FOOLED! the height is given in feet, not inches, so first convert the feet to inches, 2 ft=24 inches, so now multiply 24 times 132.665 and you get your answer 3,183.96 inches. this is the volume of the cylinder, thus telling you how much water it will hold.

if yo uwant the answer in feet, simply divide your answer by 12, to get 265.33 feet.

= 3.14*(6.5*6.5 square inches)*(24 inches)=3183.96 cubic inches
