Posted by Adrianna on Tuesday, March 20, 2012 at 2:56pm.

Write the equation for the circle with center at (- 8, - 6) and radius of 10.

(x+8)² + (y + 6)² = 10
(x+8)² + (y + 6)² = 100
(x-8)² + (y - 6)² = 100


Find the standard equation for the circle with center on the positive x-axis and passing through the origin with radius of 2.

x² + y² = 4
(x + 2)² + y² = 4
(x - 2)² + y² = 4

Choose the appropriate description for the equation.

Given: 10(x - 3)2 + 10(y + 4)2 = 100

Write the equation for the circle with center at (1, - 2) and passing through the origin.

(x - 1)² + (y + 2)² = 0
(x - 1)² + (y + 2)² = 5
(x - 1)² + (y + 2)² = 25

Choose the appropriate description for the equation.

Given: x2 + y2 = 0

Write the equation for the circle with center at (6,0) and radius of 6.

(x - 6)² + y² = 36
(x + 6)² + y² = 36
(x - 6)² - y² = 36


Write the equation for the circle with center at (0,0) and radius of 4.

x² + y² = 4
x² - y² = 16
x² + y² = 16
