Problema Solution
Find the standard form for the equation of a circle
(x-h)sqrd + (y-k)sqrd = r sqrd
with a diameter that has endpoints (-4,5) and (1,6).
h= ________
k= ________
r= ________
Answer provided by our tutors
The midpoint between the two endpoints is (-1.5, 5.5)
The distance between the endpoints is sqrt(1^2+5^2), the radius is half that.
h=-1.5
k=5.5
r= sqrt(26)/2
