Area = PI * radius^2
Circumference = 2 * PI * radius
radius = Circumference / 2 * PI
So, Area = PI * (Circumference / 2 *PI) * (Circumference / 2 *PI)
So, Area = Circumference^2 / (4*PI)
The second answer is correct.
The line is increasing by a slope of 0.6868. Y=College GPA, X=High School GPA.
An increase of 0.6868 in y is expected for every 1.0 increase in x.

Answer:
31 degrees
Step-by-step explanation:
The side lengths opposite and adjacent to the unknown angle are given. The appropriate relation is ...
Tan = Opposite/Adjacent
tan(x) = 30/50
Using the inverse tangent function, you can find x:
x = arctan(30/50) ≈ 30.964°
x ≈ 31°
The correct answer that would best complete the given statement above would be the last option: REGULAR POLYGON. <span>A polygon with congruent angles and congruent sides is called a regular polygon. It is equiangular and equilateral. A regular polygon may be a convex or a star. </span>
