Question

The center of a circle is at (–10, 6) and it has a radius of 4. What is the equation of the circle?

Answer 1

1) 

The equation of the circle with the given radius and center is D. (x+10)² + (y-6)² = 16

That is because the format of the equation of the circle is (x - h)² + (y-k)² = r²

So if you substitute in the values for the variables the answer will be choice D.

2)

Tom can walk 6 miles away because 6 is the radius in the given equation.

Hope this helps :)
