Here is my answer, I'm sorry if you didn't understand my explanation
Answer:
Exact form: = -3 + {2,-3-{2
Decimal form: x = -1.58578643
Any polygon given by a list of 2D vertex coordinates has area given by the shoelace formula.
That's the absolute value of half the sum of the cross products of the sides. We form the table of the vertices. We include the first vertex at the end, then calculate the cross product of the side, (a,b) then (c,d) gives cross product ad-bc.
cross product
-4 3 0
0 0 0
6 8 6(11)-8(2) = 66 - 16 = 50
2 11 2(3) - (11)(-4) = 50
-4 3
So the area is (1/2)(50+50) = 50
Answer: 50
Answer:
Option A is correct.
Step-by-step explanation:
The first step in the construction of a square inscribed in a circle is to draw a diameter of the circle.
Then we have to draw perpendicular bisector of the diameter using a compass.
Therefore, the perpendicular bisector will be another diameter of the circle and both the diameters will meet at the center of the circle.
Now, join the points with straight lines in order where the two diameters meet the circle. And finally, we will get a square inscribed in the circle.
Hence, option A is correct. (Answer)
Simplest form would be 58/3
