I'm guessing that you want to find the segment area of a circle that has a radius AO = 8" and a chord AB with a length of 8".

Sine angle AOD = AE / OA
Sine angle AOD = 4 / 8
Sine angle AOD = .5
arc sine (.5) = 30 degrees
So, angle AOB = 60 degrees

Circle Area = PI * radius^2
Circle Area = <span> <span> <span> 201.06</span></span></span>
Sector Area = (60/360) * 201.06
Sector Area = 33.51

Line OE^2 =  AO^2 -AE^2
Line OE^2 =  64 -16
Line OE = <span> <span> <span> 6.9282032303 </span> </span> </span>

Triangle AOB Area = OE*AE = <span> <span> <span> 6.9282032303 * 4
</span></span></span>Triangle AOB Area =  <span> <span> <span> 27.7128129211 </span> </span> </span>

Segment Area = Sector Area -Triangle AOB Area
Segment Area = 33.51 -<span>27.71
</span>Segment Area = 5.80

Given the graph below, find MN. Round to the nearest hundredth.
Galina-37 [17]

Answer:

5.39

Step-by-step explanation:

if you are trying to find MN then it means you need to find the length.

we cant use slope, but we CAN make it a triangle!

*see the attached image*

we can use A^2+B^2 to get what the hypotenuse is or C^2 is

2^2+5^2

4+25=29

the square root of 29 is 5.385

then we just round to the hundreth!

5.39

(8>5, so we bump him up)

hope this helped!
