The floor of a gazebo is in the shape of a regular octagon. The perimeter of the floor is 72 feet. The distance from the center
Katyanochek1 [597]
The length of one side of the octagon is given by:
 L = 72/8

L = 9
 Then, the apothem can be determined using the Pythagorean theorem in the following way:
 11.8 ^ 2 = (9/2) ^ 2 + a ^ 2

 Clearing to have:
 a ^ 2 = 11.8 ^ 2 - (9/2) ^ 2
 a = \sqrt{11.8 ^ 2 - (9/2) ^ 2}
 a = 10.91
 Then, the area is given by:
 A = (8) * (1/2) * (L) * (a)

 Where,
 L: length of the octagon sides
 a: apotema
 Substituting values:
 A = (8) * (1/2) * (9) * (10.91)

A = 392.76 feet ^ 2
 Answer:
 
the approximate length of the apothem is:
 
a = 10.91 feet
 
The approximate area of the floor of the gazebo is:
 
A = 392.76 feet ^ 2

One option is missing...<br><br> D) y = 11x + 5 <br><br> Please help :(
netineya [11]
The only correct answer would be D, all you do it plug in the x and y values, such as (0,5)

A) 5 = (0 + 11) - 5
     5 = 11 - 5
     5 = 6

B) 5 = 11(0) - 5
     5 = 6

C) 0 = 11(5) + 5
     0 = 55 + 5
     0 = 60

D) 5 = 11(0) + 5
     5 = 5
