The area of a circle is 17 square meters. What is its circumference?
\n" ); document.write( ".
\n" ); document.write( "Area = (pi)R^2
\n" ); document.write( "where
\n" ); document.write( "R is radius
\n" ); document.write( "pi is a constant of 3.14
\n" ); document.write( ".
\n" ); document.write( "Substitute in what we know:
\n" ); document.write( "17 = (3.14)R^2
\n" ); document.write( "R^2 = 17/3.14
\n" ); document.write( "R^2 = 5.414
\n" ); document.write( "R = 2.327 meters
\n" ); document.write( ".
\n" ); document.write( "Circumference for any circle is:
\n" ); document.write( "circumference = (pi)D = 2R(pi)
\n" ); document.write( "where
\n" ); document.write( "D is diameter
\n" ); document.write( "R is radius
\n" ); document.write( ".
\n" ); document.write( "Since we now know R, substitute it in:
\n" ); document.write( "circumference = 2R(pi)
\n" ); document.write( "circumference = 2(2.327)(3.14)
\n" ); document.write( "circumference = 14.612 meters\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
