Question

A company rents water tanks shaped like a cylinders. Each tank has a diameter of 12 feet and a height of 3 feet. The cost is $2 per cubic foot. How much does it cost to rent one water tank?

Answer 1

Answer:

$\ 678.58$

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

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

in this problem we have

$r=12/2=6\ ft$ -----> the radius is half the diameter

$h=3\ ft$

substitute

$V=\pi (6^{2})(3)=339.29\ ft^{3}$

step 2

Find the cost

$339.29\ ft^{3}*2\frac{\ }{ft^{3}}=\ 678.58$
