Coordinates 36751

Calculate the circle's length and determine the coordinates of the center of the circle when given its diameter XY, X / -3.2 / and Y / -3, -4 /.

Correct answer:

x =  -3
y =  -1
o =  18.8496

Step-by-step explanation:

X=(3,2) Y=(3,4)  x=(Xx+Yx)/2=((3)+(3))/2=3
r=(xXx)2+(yYy)2=((3)(3))2+((1)(4))2=3  o=2π r=2 3.1416 3=18.8496
