Question

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.

Answer 1

Circle F. The segment through point F is a diameter of length 20, so the radius = 20/2 = 10.
