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
Answer:
I hope this is correct but 8.5 or 8 1/2 Units
He should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents
A
We notice a factor of 2x in both
2x(5x^2+4x-3)
trial and error
(5x-3)(x+1) yeilds 5x^2+2x-3, nope
(5x+3)(x-1) yeilds 5x^2-2x-3, nope
(5x-1)(x+3) yeilds 5x^2+14x-3, nope
(5x+1)(x-3) yeilds 5x^2-14x-3, nope
simplest form is
2x(5x^2+4x-3)
