Answer 2

i want this one please

Answer 3

first if find the midpoint, which is
\[(\frac{-4+1}{2},\frac{-8+0}{2})\]

Answer 4

ok fine

Answer 5

\[d=\sqrt{(-4-1)^2+(-8-0)}^2}=\sqrt{25+64}=\sqrt{89\] is the diameter
and the radius is \[\sqrt{89\]/2
he already found the center above
so the equation is (x-(-3/2))^2+(y-(-4))^2=89/4

Answer 6

oops the radius is sqrt{89}/2
it messed up

Answer 7

if u can't read the messed up code
i just found the length of the diameter using the distance formula
