Find the diameter of a cone that has a volume of 29.31 cubic inches and a height of 7 inches. use 3.14 for pi.. 4 inches. 2 inches. 8 inches. 6 inches

First option.

Step-by-step explanation:

The formula that is used to calculate the volume of a cone is:

Where "V" is the volume, "r" is the radius and "h" is the height.

In this case we know that we must used 3.14 for , and:

Then, we can substitute values into the formula:

Now we must solve for "r":

Since the diameter is twice the radius, we get that the diameter of the cone is:

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.
