find the length of the line joining the 2 points and divide the answer by 2
Um, not really sure what that means
Find the distance between the points and divide by 2

so that would bewhat around4ish
the formula for the length of a line joining (x1,y1) and (x2,y2)
= sqrt [(x2-x1) ^2 + y2-y1)^2] which is the Pythagoras theorem
ok well I got 2
hope this helps
Use the distance formula to find the length of the diameter between these two points.
d = √[ (-2-3)^2 + (4-8)^2 ]
d = √[ (-5)^2 + (-4)^2 ]
d = √( 25 + 16 )
d = √( 41 ) = 6.40312424 = diameter.
the radius is 1/2 the diameter.
6.40312424/2 = 3.20156212.
wow.. Hopefully that's correct lol that looks about right! Thanks!
