\n" ); document.write( "If the volumes and the heights are both equal, then the areas of the bases are equal.

\n" ); document.write( "The area of the base of the cone is \"pi%28r%5E2%29\"; the area of the base of the pyramid is 154 sq cm. So

\n" ); document.write( "\"%2822%2F7%29%28r%5E2%29+=+154\"
\n" ); document.write( "\"r%5E2+=+154%287%2F22%29+=+7%2A7\"
\n" ); document.write( "\"r+=+7\"

\n" ); document.write( "ANSWER: The radius of the base of the cone is 7cm.
