Acompany 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?

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 =  

Here, take π = 22/7

So, Volume  =

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

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
