We are given equation .
We need to check the given table.
We have x=-2,-1,0,1,2 in the given table.
Plugging x=-2,-1,0,1,2 in the given equation
For x=-2
y = -3 (-2)^2 = -3(4) = -12
For x =-1
y = -3 (-1)^2 = -3(1) = -3
For x =-0
y = -3 (0)^2 = -3(0) = 0
For x =1
y = -3 (1)^2 = -3(1) = -3
For x =2
y = -3 (2)^2 = -3(4) = -12.
Therefore, correct table is
<h3> x y (x,y)</h3><h3>_____________</h3><h3> -2 -12 (-2,-12)</h3><h3> -1 -3 (-1,-3)</h3><h3> 0 0 (0,0)</h3><h3> 1 -3 (1,-3)</h3><h3> 2 -12 (2,-12).</h3><h3>________________</h3>Answer: The area of one sector is 22.6 sq. mm.
Step-by-step explanation: Given that a circle with radius 12 mm divided into 20 sectors of equal area.
We are to find the area of one sector to the nearest tenth.
The AREA of a circle with radius 'r' units is given by
Here, the radius of the circle is
r = 12 mm.
Therefore, the area of the circle will be
Since the whole circle is divided into 20 equal sectors.
So, the area of one sector is
Thus, the area of one sector is 22.6 sq. mm.
