**Question description**

the endpoints of the chord are the points where the line x=1 intersects the circle x2+y2=9 What is the length of the chord? | A coordinate system has a horizontal x-axis labeled from negative 4 to 4 in increments of 1 and a vertical y-axis labeled from negative 4 to 4 in increments of 1. A circle is drawn with a center at the origin and radius 3. A vertical line passes through the point (1,0) and is labeled "x equals 1." |

The length of the chord is approximately

(Round to the nearest tenth as needed.)
