Equations of Circles

Multiple Choice

If the center of the circle is (3, 5) then the first part of the equation will be:

( x + 3 )² + ( y + 5 )²

( x - 3 )² + ( y - 5 )²

( x + 3 )² + ( y - 5 )²

Multiple Choice

If the center of the circle is (-3, -5) then the first part of the equation will be:

( x + 3 )² + ( y + 5 )²

( x - 3 )² + ( y - 5 )²

( x + 9 )² + ( y + 25 )²

( x - 9 )² + ( y - 25 )²

Multiple Choice

If the radius of a circle is 4, then the last part of the equation will be:

= 16

= 4

= 2

= 8

Multiple Choice

If the radius of a circle is 3, then the last part of the equation will be:

= 9

= 3

= 6

= 12

Multiple Choice

If the center of the circle is (6, 7) and the radius is 6, the correct equation will be:

( x + 6 )² + ( y + 7 )² = 6

( x - 6 )² + ( y - 7 )² = 6

( x - 6 )² + ( y - 7 )² = 36

( x - 6 )² + ( y - 7 )² = 12

Multiple Choice

If the center of the circle is (2, 3) and the radius is 2, the correct equation will be:

( x + 2 )² + ( y + 3 )² = 2

( x - 2 )² + ( y - 3 )² = 4

( x - 2 )² + ( y - 3 )² = 2

( x + 2 )² + ( y + 3 )² = 4
