Let x---------> radius of the cylinder y---------> the height of the cylinder
we know that x=2y [surface area of cylinder]=2*[pi*r²]+2*pi*r*h surface area=108*pi m² r=x h=y x=2y 108*pi=2*[pi*(2y)²]+2*pi*(2y)*y 108*pi=8*pi*y²+4*pi*y² 108*pi=12*pi*y² y²=108/12 y²=9----------> y=√9--------> y=3 m x=2y-------> x=2*3-----> x=6 m
