The diameter of a circle has end points who’s coordinates are r(-2,2) and s(4,2) what is the radius

2.5

Step-by-step explanation:

First find the length of RS

x2 = 4

x1 = - 1

y2 = 2

y1 = 2

RS^2 = (2 - 2)^2 + (4 - -1 ) ^2

RS^2 = 0 + 5^2

RS = sqrt(5^2)

RS = 5

That is the length of the diameter. The radius is 1/2 that

r = d/2

d = 5

r = 5/2

r = 2.5

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
