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:

The total cost of the cylindrical tank is $226.28

Step-by-step explanation:

Dimensions of the tank are:  radius = 3 ft , height = 2 ft

Cost per cubic foot = $4

Now, total volume of the cylindrical tank =  $\pi \times r^{2}h$

Here, take π = 22/7

So, Volume  = $\frac{22}{7} \times (3)^{2} \times (2) = \frac{22 \times 9 \times 2}{7} = \frac{396}{7} = 56.57 cubic ft$

So, the volume of the tank = 56.57 cubic feet.

Now, cost per cubic foot = $4

Hence, the total cost of the tank = Total Volume of the tank x cost per foot

                                                       = 56.57 x 4 = $226.28

So, the total cost of the cylindrical tank is $226.28
