The two straight edges of the shape correspond to the original circle's radius, 5.5 cm. We're told this sector has area 30.25 cm^2, which we will use to determine the measure of the central angle subtended by the arc (the remaining edge of the shape).
The complete circle has an area of 
, which corresponds to a "central angle" of 
. Then if 
is the central angle of this sector, we have
The complete circle has a circumference of 
. Then if 
is the length of the sector's arc, we get
So the sector has a total perimeter of
5.5 cm + 5.5 cm + 11 cm = 22 cm
10 to the exponent 2 is equal to 100, so 8.7 x 100 is equal to 870
I know the correct answer but I need you to first answer my math questions
Answer:
y = 1
Step-by-step explanation:
Slope is written in the form y=mx+b. Where m is the slope and b is the y-intercept.
When there isn't a slope, as in the line is flat and it isn't moving up or down, you wouldn't write anything for it. You would just write y equals the y-intercept (y = b).
Likewise, if the y-intercept is at (0,0), then you'd only write y equals the slope (y = mx).
Hopefully this makes sense :)
Btw, I also answered in the main comments earlier, so you can check that out as well.
