Answer:
Given the equation, the radius of the circle is 7.
Step-by-step explanation:
We are given the equation, x² + y² = 49.
In order to find the radius, we have to calculate the square root of 49. This is because the original form of the equation is x² + y² = r².
[tex]\sqrt{49} = 7[/tex]
So, the radius of the circle is 7.
