Question 576486
<font face="Times New Roman" size="+2">


*[tex \LARGE \pi], a trancendental irrational number approximated by the rational number 3.14, is the ratio between the circumference and the diameter of any circle.  The diameter of a circle is 2 times the radius, so by multiplying the radius of 4 by 2, you managed to discover the measure of the diameter, which is, indeed, 8. But in order to determine an approximate value of the circumference of the circle, that is, the distance around the circle (as opposed to the distance straight across through the center which is the diameter).


So what you have to do is multiply 8 times 3.14 to get a two-decimal place accurate approximation of the measure of the circumference.


By the way, the only way to represent the circumference exactly is to write *[tex \LARGE 8\pi]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
