The diameter of a circle is 14 centimeters. Enter the circumference of the circle, in centimeters. Round your answer to the nearest hundredth.

The answer when using the pie button on the calculator would be 43.98 and that's already rounded to the hundredths place. The answer if you were using 3.14 is 43.96.

Step-by-step explanation:

Circumference =2 times pie times radius

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
