The inside floor area of a silo is 20sf and 35ft high. What is the inside
\n" ); document.write( "wall area.
\n" ); document.write( "-------------
\n" ); document.write( "Assuming it's round (a cylinder with a flat top):
\n" ); document.write( "Find the radius.
\n" ); document.write( "\"Area+=+pi%2Ar%5E2+=+20\"
\n" ); document.write( "\"r+=+sqrt%2820%2Fpi%29\"
\n" ); document.write( "r =~ 2.523 ft
\n" ); document.write( "---
\n" ); document.write( "For the vertical wall:
\n" ); document.write( "\"Area+=+2pi%2Ar%2Ah+=+2%2Api%2A2.523%2A35\"
\n" ); document.write( "Area = 554.87 sq ft
\n" ); document.write( "----------
\n" ); document.write( "If the top is flat, that's another 20 sq ft
\n" ); document.write( "---
\n" ); document.write( "If the top is a hemisphere:
\n" ); document.write( "\"Area+=+2pi%2Ar%5E2\"
\n" ); document.write( "= another 40 sq ft
\n" ); document.write( "
\n" );
