How do I find the area of a circle with the circumference of 18.84 units

A circle with radius r has a circumference of 2πr.

2πr = 18.84  ==>  r = 18.84/(2π) ≈ 2.998 units

The same circle has area πr ² sq. units. So the area is

π (2.998)² ≈ 28.246 sq. units

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
