The arc PQ forms the circumference of the circlular base of the cone.
\n" ); document.write( "The circumference (C) of a circle is given by:
\n" ); document.write( "\"C+=+%28pi%29D\" Where D is the diameter and \"C+=+10\"cm. Solve this for D:
\n" ); document.write( "\"10+=+%28pi%29D\" Solve for D.
\n" ); document.write( "\"D+=+10%2Fpi\"
\n" ); document.write( "
\n" );
