QUIZ Equation of Circles 10.7

Write the equation of a circle with center (7, 0) with radius 3. 

• (x - ^7)^2 + y^2 = 9
• x^2 + (y -7)^2 = 9
• (x - 7)^2 + y^2 = 3
• x^2 + (y -7)^2 = 3

What is the equation for the circle, if it has diameter endpoints at (3,-4) and (-5,-4)?

• (x+1)² + (y-4)² = 4

• (x+1)² + (y+4)² = 16

• (x-1)² + (y-4)² = 16

• (x+1)² + (y+4)² = 4

Which graph corresponds to 
(x)²+ (y-6)²=9

• A
• B
• C
• D

What is the circle equation?

• (x+12)²+(y+9)²=17π

• (x-9)²+(y-12)²=72.25

• (x+9)²+(y+12)²=72.25

• (x-12)²+(y-9)²=17π

Select the equation of a circle that has a diameter of 12.

• (x-6)²+(y+6)²=12

• (x-12)²+(y-2)²=6

• (x+1)²+(y-12)²=144

• (x-4)²+(y-1)²=36
