The second hand of a clock is four inches long. To the nearest inch, how far does the tip of the second hand travel in 45 seconds?
\n" ); document.write( ".
\n" ); document.write( "If the tip went the entire circle of 60 seconds it would have traveled:
\n" ); document.write( "Circumference = (pi)(2r)
\n" ); document.write( "where
\n" ); document.write( "pi is 3.14
\n" ); document.write( "r is radius
\n" ); document.write( ".
\n" ); document.write( "Circumference = (3.14)(2)(4)
\n" ); document.write( "Circumference = (3.14)(8)
\n" ); document.write( "Circumference = 25.12
\n" ); document.write( ".
\n" ); document.write( "If we only traveled for 45 seconds:
\n" ); document.write( "45/60 * 25.12
\n" ); document.write( "= 3/4 * 25.12
\n" ); document.write( "= .75 * 25.12
\n" ); document.write( "= 18.84
\n" ); document.write( "To the nearest inch:
\n" ); document.write( "19 inches
\n" ); document.write( " \n" ); document.write( "
\n" );
