calculista

Answer:

[tex]\$678.58[/tex]

Step-by-step explanation:

step 1

Find the volume of the tank

we know that

The volume of a cylinder (water tank) is equal to

[tex]V=\pi r^{2}h[/tex]

in this problem we have

[tex]r=12/2=6\ ft[/tex] -----> the radius is half the diameter

[tex]h=3\ ft[/tex]

substitute

[tex]V=\pi (6^{2})(3)=339.29\ ft^{3}[/tex]

step 2

Find the cost

[tex]339.29\ ft^{3}*2\frac{\$}{ft^{3}}=\$678.58[/tex]
