Equation of the circle centered

WebThe equation, x 2 + y 2 = 64, is a circle centered at the origin, so the standard form the parametric equations representing the curve will be x = r cos t y = r sin t 0 ≤ t ≤ 2 π, where r represents the radius of the circle. Since r 2 = 64, the value of the circle’s radius is equal to r = 8. Hence, we have the parametric equations shown below. WebThe equation of the center of the circle is ( x – h) 2 + ( y – k) 2 = r 2 . Center coordinates ( h, k) are ( 3, 4), radius r = 5 units. By substituting these values for h,k, and r in the equation, we have, ( x − 3) 2 + ( y − 4) 2 = 5 …
