The circumference of a circle is 14π ft. What is the area, in square feet? Express your answer in terms of \piπ.

So then we can find r from the last equation like this:

And r is:

And then the area is given by:

And replacing the radius we got:

Then the final answer would be

Step-by-step explanation:

For this case we have the circumference of the circle given

We know that the circumference formula is given by:

So then we can find r from the last equation like this:

And r is:

And then the area is given by:

And replacing the radius we got:

Then the final answer would be

if this is really you s much. i only have 3 points left and i have 2 questions to ask

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2
