Answer:To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides. Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side.

Circumference of a circle is 2(pi)(r)
2(3.14)(7)= 43.96
So the answer is B
Answer:
The answer is A
Step-by-step explanation:
Supplementary angles are angles which add up to 180°
∠1 and ∠3 add up to 180°, so they are supplementary.
Are you looking for the amount after interest gained? If so I believe the answer would be $40.
500 x 0.04 x 2 = 40
Evaluate -(5)^2. Note that Order of Operations rules (PEMDAS) require that we perform exponentiation before multiplication.
Therefore, we evaluate 5^2 first, obtaining 25, and after that multiply this result by -1.
-(5)^2 = -25
