Given:
\n" ); document.write( "8T² = л²L
\n" ); document.write( "And,
\n" ); document.write( "L = 10
\n" ); document.write( "л = 3.14
\n" ); document.write( ".
\n" ); document.write( "Plug it in to your equation and solve for T:
\n" ); document.write( "8T² = л²L
\n" ); document.write( "8T² = л²(10)
\n" ); document.write( "T² = (л²(10))/8
\n" ); document.write( "T = sqrt[(л²(10))/8]
\n" ); document.write( "T = sqrt[л²(1.25)]
\n" ); document.write( "T = sqrt[(9.8596)(1.25)]
\n" ); document.write( "T = sqrt[12.3245]
\n" ); document.write( "T = 3.51 seconds\r
