Equation
The circle's radius is ∜5. The center is at (2, 3) which are the (h,k) values.
What is the equation, in standard form, for this circle?
The equation for the standard circle is; (x - h)2 + (y - k)2 = r2
substitute in the (h, k) values:
(x - 2)2 + (y - 3)2 = (∜ 5)2
(x - 2)2 + (y - 3)2 = 52/4
(x - 2)2 + (y - 3)2 = 51/2 and this is the answer for question # 51
