Tutorial Exercise Graph the circle. x 2 + 12 = 16 Step 1 of 2 Identify the center and radius of the given circle using the equation. Recall that the general equation of a circle centered at the origin with radius r is x2 + yz = r. The given equation is x2 + y2 = 16. Compare the given equation with the general equation to identify the center and the radius. The left sides of the equations are the same. Therefore, the center of the given circle is located at what point? ( x, y) = ( ) Setting the right sides of the equations equal to one another gives r = 16. Solve for r. To eliminate the square, take the square root of both sides. 12 = 16 VR = +V r = + Recall that r represents the radius, which must be a positive value. Therefore, what is the radius r of the circle? r = units Submit Skip (you cannot come back). MacBook Air 888 esc F7 F3 F6 F1 X- P/o @ # 2 3 4 5 W E T Y Q R U tab1.
