Algebra.Com's Answer #537355 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! The formula for circumference of a circle is C=Pi*Diameter (or 2 Pi R) \n" ); document.write( "If the radius is 2x, simply insert that value into the formula to get \n" ); document.write( "C = 2 Pi (2X) or C = 4 Pi X \n" ); document.write( " |
