x2 + y2 − 6x + 8y = 144
The equation of a circle in the xy-plane is shown
above. What is the diameter of the circle?
Estimated Difficulty: Hard
Key: 26
Completing the square yields the equation
(
x − 3)
2
+ (
y + 4)
2
=
169
, the standard form of an
equation of the circle. Understanding this form
results in the equation
r
2
=
169
, which when solved
for
r
gives the value of the radius as
13
. Diameter
is twice the value of the radius; therefore, the
diameter is
