I need to find the perimeter and area of the regular polygon.

mezya [45]

The area of a polygon is given by the formula Area = ap/2 where a is the length of the apothem and p is the perimeter. The apothem is a line from the center of the polygon perpendicular to a side.

Depending on the formula you know, you can find the length of a side in 1 of 2 ways.

The first way uses a triangle. Using the radius of the polygon you can create 8 congruent triangles. The center angle will be 360 / 8 = 45 and two side lengths of 20. You can find the length of the base using the law of cosines.

c^2 = 20^2 + 20^2 - 2(20)(20)(cos 45)
c^2 = 400 + 400 - 800(cos 45)
c^2 = 800 - 800(cos 45)
c = sqrt(800 - 800(cos 45)
c = 15.31

The second way is to use this formula:
r = s / (2 sin(180 / n))
20 = s / (2 sin(180/8)
(20)(2)sin(22.5) = s
(40)sin(22.5) = s
s = 15.31

We need to calculate the perimeter. As there are 8 sides (8)(15.31) = 122.48
Now we need to calculate the apothem using

a = S / (2 tan (180 / n)
a = 15.31 / (2 tan (180 / 8))
a = 18.48

Now solve for the area

Area = ap/2
Area = (18.48)(122.48)/2
Area = 1131.72

perimeter = 122.48
area = 1131.72

The equation y=2.16x describes the weight y of x cubic pounds of pudding. Find three solutions, list them as ordered pairs and t

loris [4]

Answer:

(1,2.16), (2,4.32) and (3, 6.48).

The solution (1,2.16) means that 1 cubic units of pudding weighs 2.16 pounds.

The solution (2,4.32) means that 2 cubic units of pudding weighs 4.32 lbs.

Step-by-step explanation:

The equation y=2.16x describes the weight y of x cubic pounds of pudding.

The three solutions of this equation are (1,2.16), (2,4.32) and (3, 6.48).

Now, solution (1,2.16) means that 1 cubic unit of pudding weighs 2.16 pounds.

Again, solution (2,4.32) means that 2 cubic units of pudding weigh 4.32 lbs. (Answer)
