Question

A company rents water tanks shaped like cylinders. Each tank has a radius of 3 feet and a height of 2 feet. The cost is $4 per cubic foot. How much does it cost to rent one water tank?

Answer 1

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

$56.52(4)=\ 226.08$
