In teaching my ASVAB prep course, I remind my students to study the formulas for area, volume, and surface area to help improve their Math Knowledge score on the ASVAB.  In working as an ASVAB tutor, I tell my students that not knowing their formulas is like giving away free points.  Today’s question is about a circle.

If the diameter of a circle is 15, what is the radius?

Do you know the answer to this question?  The answer will be posted tomorrow.
