The volume of a cylinder is 540x ft. the height is 15 ft. what is the diameter of the cylinder?

ANSWER

12 ft

EXPLANATION

The volume of a cylinder is calculated using the formula

From the question, the volume was given as 540π ft³ .

The height is given as 15 ft.

We substitute the values to obtain:

This implies that;

We simplify to get;

Take positive square root to obtain:

The diameter is twice the radius.

Hence the diameter is 12ft

The answer is:

The diameter of the cylinder is equal to 12 feet.

Why?

To find the diameter of the cylinder we need to use the formula to calculate its volume.

So,  we have:

We are given the following dimensions of the cylinder:

Now, using substituting and isolating the radius in order to find the diameter, we have:

Therefore, we have:

We know the radius, then, calculating the diameter we have:

Hence, we have that the diameter of the cylinder is equal to 12 feet.

Have a nice day!

answer: was that a question or answer?

step-by-step explanation:

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
