A closed tube is 10 inches long with a radius of 5 inches
\n" ); document.write( ":
\n" ); document.write( "find its surface area
\n" ); document.write( "Area of the side: circumference * length
\n" ); document.write( "Area of the ends: 2 * area of the circular ends
\n" ); document.write( ":
\n" ); document.write( "A = Side area + 2 ends area
\n" ); document.write( "A = (2*pi*5*10) + 2(pi*5^2)
\n" ); document.write( "A = 314.16 + 157.08
\n" ); document.write( "A = 471.4 cu inches
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "find its volume
\n" ); document.write( "Vol = pi*r^2*h
\n" ); document.write( "V = pi*5^2*10
\n" ); document.write( "V = 785.4 cu inches
\n" ); document.write( "
\n" );
