You can put this solution on YOUR website!
The juice can can be modelled as a cylinder.\r
\n" ); document.write( "\n" ); document.write( "Surface area of a cylinder is $\"+2%2Api%2Ar%2Ah+%2B+2%2Api%2Ar%5E2\"$
\n" ); document.write( "where r = radius and h = height of the cylinder\r
\n" ); document.write( "\n" ); document.write( "h=18 cm
\n" ); document.write( "r = diameter ÷ 2
\n" ); document.write( "r = 5/2 cm
\n" ); document.write( "r = 2.5 cm \r
\n" ); document.write( "\n" ); document.write( "Surface area of the juice can = $\"+2%2Api%2Ar%2Ah+%2B+2%2Api%2Ar%5E2\"$
\n" ); document.write( "= $\"2%2Api%2A2.5%2A18+%2B+2%2Api%2A2.5%5E2\"$ cm^2
\n" ); document.write( "= 332 cm^2 \n" ); document.write( "
