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

Cost to rent one tank=226.08 Dollars

Explanation:

Radius of the cylindrical tank=3 feet

Height of the tank= 2 feet

Cost to rent one tank= Volume of one tank * cost to rent one cubic feet of volume

Volume of the cylindrical tank:

=
`\pi r^2`

As,
`\pi =(22)/(7)=3.14`

Putting the values in the formula:

Volume of the tank:

`=3.14*(3*3)*2\\\\=3.14*9*2\\\\=3.14*18\\\\=56.52feet^3`

Cost to rent one cubic feet= 4 Dollars

Cost to rent 56.52 Cubic feet of one tank;

= 4*56.52

=226.08 Dollars
