Yesterday I presented a question about the diameter and radius of a circle.  If the diameter is 15, what is the radius?

In working as an ASVAB tutor, I teach my students the necessary formulas to help improve their Math Knowledge score.  Geometry topics require the knowledge of the formulas since no formulas will be provided during the test.  Students who attend my ASVAB prep course receive all the necessary formulas from me. Yesterday I presented a question about the diameter and radius of a circle.  If the diameter is 15, what is the radius?

The radius is half the diameter, so the radius is 7.5

Did you know the correct answer?
