Question

Determine the equation of the circle graphed below. Circle Standard Form: Center: (h, k). Radius: r. (x-h) ^2+(y-k) ^2=r^2. Center: (3, 5). Radius: 5.

Answer 1

Using center (3, 5) and radius 5:

Standard form: (x - 3)^2 + (y - 5)^2 = 25

Expanded (general) form: x^2 + y^2 - 6x - 10y + 9 = 0
