Answer:
3(3×2x + 0)(3x²+2)² = 18x(3x²+2)²
A regular polygon<span> is equilateral (it has equal sides) and equiangular (it has equal angles). To </span>find the area of a regular polygon<span>, </span>you<span> use an apothem — a segment that joins the </span>polygon's<span> center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem).
Hope this helps tho I cant help with #2 sorry</span>
There would be no pennies
Answer:
5.25 is the lenght of the arc AB.
Step-by-step explanation:
First, since we are told the answer should be expressed in radians, we need to convert the arc angle into radians, we do that by multiplying the angle by π and dividing by 180.
60° * π/180 = 1.05rad
Now, there is a simple formula to calculate the arc lenght, A = Ф*r, where:
A = arc lenght
Ф = arc angle (60°=1.05rad)
r = radius (5cm)
A = 1.05*5cm
A = 5.25cm
