The center of a circle is located at (-10, 3). Its diameter is 26 units. What is the equation of this circle in standard form?

Question

[Enter your answer as (x - h)² + (y - k)² = r².]

Answer 1

standard form is (x-h)^2+(y-k)^2=r^2 to find the radius take the diameter which is 26 and divide by 2 so 26/2=13 and since the center point is (h, k) or (-10,3) so then (x--10) or (x+10)^2+(y-3)^2=13^2-> (x+10)^2+(y-3)^2=169 and this is the equation is standard form.

Answer 2

Radius is 6. Square, Insert in formula.
