The distance from the center of the pipe to the surface
\n" ); document.write( "of the water in the pipe is $\"+25+-+18+=+7+\"$ cm
\n" ); document.write( "-----------
\n" ); document.write( "Also, the distance from the center of the pipe to where
\n" ); document.write( "the surface contacts the pipe is the radius, $\"+25+\"$
\n" ); document.write( "This forms a right triangle when you include the surface
\n" ); document.write( "-----------
\n" ); document.write( "Call ( center of water surface to where surface meets pipe ) = $\"+x+\"$
\n" ); document.write( "Now I can say
\n" ); document.write( " $\"+25%5E2+-+7%5E2+=+x%5E2+\"$
\n" ); document.write( " $\"+625+-+49+=+x%5E2+\"$
\n" ); document.write( " $\"+x%5E2+=+576+\"$
\n" ); document.write( " $\"+x+=+24+\"$
\n" ); document.write( "The is 1/2 of the width of the water's surface, so
\n" ); document.write( " the width of the water surface across the pipe is 48 cm\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
