Question

Given the equation of the circle (x – 9)2 + y2 = 484, the center of the circle is located at __________, and its radius has a length of __________ units.

Answer 1

A. (0, 9) and 22 B. (9, 0) and 22 C. (0, 9) and 23 D. (9, 0) and 23

Answer 2

Formula for a circle with radius \(r\) and center \((h,k)\) is \[(x-h)^2+(y-k)^2=r^2\]

Read off the values and choose the right answer.

Answer 3

The center is (9,0) and the radius is :
\[\sqrt{484}=22\]
