TEST Geometry Unit 9: Circle Equations
Multiple Choice: Identify the choice that best completes the statement or answers the question:
Find the center and radius of the circle with equation (x - 3)^2 + (y + 10)^2 = 36.
a) center (-3, 10); r = 36
b) center (3, -10); r = 36
c) center (10, -3); r = 6
d) center (3, -10); r = 6
Write the standard form of the equation with center (-10, 8) and r = 9.
a) (x + 10)^2 + (-8)^2 = 9
b) (x - 10)^2 + (y + 8)^2 = 9
c) (x - 8)^2 + (y + 10)^2 = 81
d) (x + 10)^2 + (-8)^2 = 81
