Answer:
25.9666 m
Step-by-step explanation:
The 4 arches combine to for a circle, so then you can find the area of the shaded region by subtracting the area of the square from the area of the circle.
The formula for area of a circle is A=r^2
Since the radius of the circle would be 11/2 or 5.5, the area if the circle would be x 5.5^2. This equals 95.0334.
The area of the square would be 11 x 11 = 121.
The 121-95.0334= 25.9666 m
Sum of all interior angles = ( n - 2) x 180
Since Octagon = 8 sides,
Sum of all interior angles = ( 8 - 2) x 180 = 1080
z = 1080 ÷ 8 = 135°
Answer: z = 135°
Answer:
0.28
Step-by-step explanation:
Answer:
64 pi
Step-by-step explanation:
Area of a circle is pi(r) ^ 2
The radius is half the diameter, so it would be 8 mi.
Pi ( 8 ) ^ 2
Pi ( 64 )
It would be 64 pi
0.5 = 1/2 = 2/4 = 4/8 = 8/16 = 16/320.75 = 3/4 = 6/8 = 12/16 = 24/32
Then the fractions in between are 5/8, 9/16, 11/16, 17/32, 19/32, 21/32, 23/32
