A circle is a curve sketched out by a point moving in a plane. The circumference of the ring of fire is 6.2831 meters.
<h3>What is a circle?</h3>
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The circumference of the ring if the radius is 1 meter is,
Circumference of the ring = 2πr = 2 × π × 1 = 6.2831 meters
Hence, the circumference of the ring of fire is 6.2831 meters.

Let me start from the meaning of half plane.you must have learned that there are two axes X and Y axes which includes positive X axes and negative X axes and there is positive Y axes and negative y axes. So there are four quadrants which i have explained in the figure. I have explained the meaning of Half plane in the Diagram also. Half plane=Figure obtained by covering any two adjacent regions of the coordinate axes.So we get four half planes.
Now your question is k is a half plane determined by QR, such that 0<x≤180 and there is exactly one ray QRP that lies in k
So, 
EFGH is a dilation and rotation of ABCD.
The shortest side of the smaller figure corresponds to the shortest side of the largest one, the largest sides correspond, etc.
AB -> EF
BC-> FG
CD->GH
DA->HE
Corresponding angles are congruent in dilations.
Angle A = angle E
Angle B= angle F
Angle C = angle G
Angle D = angle H
Explanation:
EFGH is a dilation and rotation of ABCD. If you take one of the figures, rotate it 180 degrees, and lay it on top of the other figure, the corresponding sides and angles will line up.
