Answer:

$\$226.08$

Step-by-step explanation:

step 1

Find the volume of the tank (cylinder)

The volume of cylinder is given by the formula

$V=\pi r^{2}h$

we have

$r=3\ ft\\h=2\ ft\\\pi=3.14$

substitute

$V=(3.14)(3)^{2}(2)$

$V=56.52\ ft^3$

step 2

Find the cost of rent one tank

Multiply the volume of one tank by the unit rate of $4 per cubic foot

$56.52(4)=\$226.08$
