HELPPPPP

[cyan dove]

I got (x-2)^2 + (y+4)^2 = root80 but the correct answer has 20 instead where I put root80

how long is the line segment?

as in distance?

yh

i got root80

ans is 20 tho

root (x2-x1)^2 + (y2-y1)^2

i used that

okay

so the diameter

yeah

is root 80

or 4root5

So the radius is hlf of that

ye

So its 2root5

ohhhhhhh

And the circle equation is (x-a)^2+(y-b)^2=r^2

So in our ewuation we want to square the radius

I see I see I see

And 2 root 5 swuared is 20

yes

ok thanksssss
