Algebra.Com's Answer #27233 by psbhowmick(878)![]() ![]() You can put this solution on YOUR website! If radius of a circle is 'r' then the circumference = \n" ); document.write( "Measurement of waist is 20\" means the circumference is 20\". \n" ); document.write( "Thus, \n" ); document.write( "or \n" ); document.write( "or r = 3.183\"\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the reqd. radius is 3.183 inches. \n" ); document.write( " |
