Answer:
multiply pi (3.14) by 2 and that would give it to you.
Step-by-step explanation:
Using the mid-point concept, it is found that point B is located at coordinates (-6.5, 0).
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
The center is the midpoint of the two coordinates of the diameter, hence:

For the x-coordinate:

x + 0.5 = -6
x = -6.5
For the y-coordinate:

y + 6 = 6
y = 0

Well since the formula for the arithmetic mean is

thourgh

will be each of the numbers (2, 63, 88, 10, 72, 99, 38) and n would be the number of numbers being added. You have 7 numbers being added making n 7 so your equation would be
Since you can see that the triangle is isosceles triangle the length of the 2 side will be same
2n+9=7n-18
9+18=7n-2n
27=5n
n=27/5
