The graph of a quadratic function is a parabola. The axis of symmetry<span> of a parabola is a vertical line that divides the parabola into two congruent halves. The </span>axis of symmetry<span>always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the </span>axis of symmetry<span> of the parabola.</span>
Circumference = 2 pi r = 20 pi
corresponding to 360 degrees
so an arc of 4pi feet will have a degree measure of 5pi / 20pi * 360 = 1/4 * 360 = 90 degrees
