Which circle has a radius that measures 10 units? Circle D is shown. A line segment goes from one point to another point on the
circle and has a length of 10. Circle F is shown. A line segment goes from one point to another point on the circle and goes through point F. It has a length of 20. Circle G is shown. A line segment goes from one point to another point on the circle and goes through point G. It has a length of 10. Circle H is shown. A line segment goes from one point to another point on the circle and has a length of 20.
There's no picture attached, so I can't tell you which circle that is, but remember that the radius is equal to half of the diameter. The diameter is a segment on the interior of a circle that passes through the center. You could also find a ten-unit-long line with a segment from the center of the circle to any point on the circle, because that is the radius. If it doesn't pass through the center, it's a chord, not a diameter, so it doesn't count!
