Answer & Step-by-step explanation:
In order to solve this problem, it is important that we know the original form of this equation.
<em>(x - x1)² + (y - y1)² = r²</em>
The equation we are given is: <em>(x - 1)² + (y + 20)² = 196</em>
Now that we know the original equation and the given equation, then we can conclude that the center of the circle is (1, -20). We can find the radius by calculating the square root of 196.
√196 = 14
So, the radius is 14.
Now, based on the given information, we know that the center of the circle is (1, -20) and the radius of the circle is 14.
