R = 13.1
so
<span>diameter = 13.1 x 2 = 26.2 km
</span>circumference = 2 pi r = 26.2 pi km
or
circumference = 26.2 x 3.14 = 82.27 km
A circles DIAMETER is twice as long as its radius
Hope this helps you :)
The y-intercept of the line that is shown if the slope is 0 is: 2.
<h3>What is the Y-intercept of a Graph?</h3>
The y-intercept of a graph is the value of y when x = 0, which is the point on the vertical axis (y-axis) where the line intercepts.
The graph given is an horizontal line having a slope value of 0. The equation of the line is therefore, y = 2.
Thus, from the given graph, the y-axis is intercepted by the line at y = 2. At this point where y = 2, the corresponding value of x is 0.
Therefore, the y-intercept of the line that is shown if the slope is 0 is: 2.

<span>An isosceles triangle could have rotational symmetry if it were also an equilateral triangle. An isosceles triangle is a triangle with at least two equal sides. An equilateral triangle is a triangle with exactly three equal sides. By definition, all equilateral triangles are also isosceles triangles.</span>
