SUBMIT ANSWER

When using the given information, the diameter of the circle is going to be 28 mL.

Step-by-step explanation:

First, we need to know the formula for finding the area of a circle.

Now, we need to rearrange the formula so we can find the radius.

Next, we plug in the given area into the equation.

Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.

So, the diameter of the circle is 28 mL
