Manuel wants to buy a window shade to cover the window and frame shown. The window is in the shape of a regular octagon.
The radius of the window, including the frame, is 2 ft, and the measure of each edge of the octagonal frame is 1.52 ft.

What is the approximate area of the window that needs to be covered, including the frame?
2 ft2
7 ft2
11.2 ft2
22.5 ft2

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

probably the last option

step-by-step explanation:

if you would like with a question it is easy to get an answer by including some or multi choice options

step-by-step explanation:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
