A, area of whole figure
\n" ); document.write( "p, perimeter
\n" ); document.write( "r, radius of connected semicircle, also one of the rectangle part's dimensions
\n" ); document.write( "h, height dimension perpendicular to r
\n" ); document.write( "-
\n" ); document.write( "A=24\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "QUESTION: What is perimeter as a function of r?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"A=%281%2F2%29pi%2Ar%5E2%2Bh%2Ar\"
\n" ); document.write( "\"A=%28pi%2F2%29r%5E2%2Bh%2Ar\"
\n" ); document.write( "Solve this for h.
\n" ); document.write( "\"hr=A-%28pi%2F2%29r%5E2\"
\n" ); document.write( "\"h=A%2Fr-%28pi%2F2%29r\"-----this formula for h will be used.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"p=2h%2Br%2Bpi%2Ar\"
\n" ); document.write( "-
\n" ); document.write( "Substitute for h.
\n" ); document.write( "\"p=2%28A%2Fr-%28pi%2F2%29r%29%2Br%2Bpi%2Ar\"
\n" ); document.write( "\"p=2A%2Fr-pi%2Ar%2Br%2Bpi%2Ar\"
\n" ); document.write( "\"p=2A%2Fr-pi%2Ar%2Bpi%2Ar%2Br\"
