Solution: The pipe is in shape of cylinder, where the surface area is:\r
\n" ); document.write( "\n" ); document.write( " \"+S+=+2%2A%28pi%29%2AR%2AH+\", where R is the base radius and H is the length of pipe.
\n" ); document.write( " \"+S=+2%2A%283.14%29%2A%280.25%29%2A%28100%29\" (3 inches = 0.25 feet)\r
\n" ); document.write( "\n" ); document.write( " S=157\r
\n" ); document.write( "\n" ); document.write( "Answer:The exposed surface area of the pipe is 157 square feet.
