document.write( "Question 576486: If my paper says to find the circumference of a circle whose raius is 4 inches, what do I do? I understand that you multiply the 4 by 2, but it also says to use 3.14 for pi. I do not understand what 3.14 has to do with the problem when it wants me to show the solution/formula. This is what I did: 2×4 = 8 inches \n" ); document.write( "
