Hi there, \n" ); document.write( "Circumference = pi * diameter \n" ); document.write( "25.12 = pi * diameter \n" ); document.write( "Diameter = 25.12/pi \n" ); document.write( "Diameter = 8 cm \n" ); document.write( "Radius = 4 cm. \n" ); document.write( "Surface Area of a cylinder \n" ); document.write( "= 2*pi*r*h + 2*pi*r^2 (* times) \n" ); document.write( "= 2*pi*4*60 + 2*pi*4^2 \n" ); document.write( "= 1507.96 + 100.53 \n" ); document.write( "= 1608.49 cm^2 \n" ); document.write( "Hope this helps :-) \n" ); document.write( " |
