I think 4.12 if thats what your asking for.
The area of a circle is given in terms of circumference by
.. A = C²/(4π)
Then the ratio A/C is
.. A/C = C/(4π)
Substituting the given information, we have
.. 16 cm = C/(4π)
.. C = (4π)*16 cm = 64π cm
.. C ≈ 200.96 cm
It would be the Second answer choice
The slope seems to go up by 2 then for over 1
And the y intercept has to be a positive number, so y = 2x + 1 is the only logical answer
.0029 see picture below for step by step explanation.
Those are right ...........................
