An important part of Mathematics Knowledge is the memorization of a variety of formulas.  Reviewing geometry formulas is a must.  This problem involves one of the many formulas I review in my ASVAB prep course.  This question requires knowing the formula for the area of a circle.  In order to help my students to improve their ASVAB math knowledge score, I remind students to be solid on their formulas.  Formulas are not provided on the test.  Anyone who tutors for the ASVAB knows the importance of knowing all the math formulas.  Can you solve this problem?  The answer and explanation will be presented tomorrow.
