Based on the graph, point O is the center of the circle.
Segment BC is a chord of the circle that passes through point O, it is a diameter.
Segment OA is a radius of the circle.
The correct statement for this problem is:
<span>Amy walks a distance equal to the diameter, and Fraser walks a distance equal to the radius of the lawn.</span>
Let
The origin of coordinates the tree
r1 = vector position of the child 1.
r2 = vector position of the child 2
Child 1:
r1 = (12i + 12j)
Child 2:
r2 = (-18i + 11j)
The scalar product will be given by:
r1.r2 = ((12) * (- 18)) + ((12) * (11)) = - 84
The scalar product of their net displacements from the tree is -84m ^ 2

We have,


Answer:
I got 1.79
Step-by-step explanation:
If you're saying 179 divided by 10 to the second power it would be 1.79.
