Question
Solution 1
The equation of a circle centered at the origin is given by x² + y² = r², where r is the radius of the circle. In this case, the equation is x² + y² = 144. Therefore, r² = 144. To find r, we take the square root of both sides, which gives r = √144 = 12. So, the radius of the circle is 12.
