Volume of cylinder = [pi] r[sqr] h = 1000
[pi] r h = 1000/r —— (equation 1)
Surface area of Cylinder S(r)= 2 [pi] r h + 2 [pi] r [sq]
{height x perimeter of circle} + {twice the area of circle}

so S(r) = 2 {[pi] rh} + 2 [pi] r [sq] ———- (equation 2)
sub equation 1 in curly bracket in equation 2
S(r) = 2 {1000/r} + 2 [pi] r [sq]./answer.
