Prove or disprove that the point (√51,7) lies on the
circle centered at the origin and containing the point (6,8).
SOLUTION
The circle centered at the origin and containing the point (6,8) has the
following radius.
r=√(x −h)² + (y-k)² where x = ₁ h = ₂y=
and k =
So, r =
and a point lies on the circle if and only if the distance from
that point to the origin is
The distance from (√51, 7) to the origin is
W
d = √(x −h)² + (y-k)² where x = ₁ h = ₂ y=
and k =
So, d =
So, the point (√51, 7) lies on the circle centered at the origin and containing
the point (6,8).
