In the standard (x, y) coordinate plane, what is the area of the circle x^2 + y^2 = 169?

169π

Step-by-step explanation:

circle eq: (x-a) ² + (y-b) ²=r², where (a, b) is center and r is radius

r²=169

r = ±13

since a radius length must be positive, r = + 13, not - 13

A of circle: πr²

r = 13

169π

given that the circle eq has r², you could've noticed that you can take the constant in the circle eq and multiply that by π to get the same answer
