<PRE><B>Question 763977</B>
Diameter = x
Radius = x/2
Height = x
Volume = Pi*(x/2)^2*x
128Pi = Pi*x/4 * x
  128 = x^3/4
   x^3 = 4 * 128
    x^3 = 512
     x = cube root of 512
     x = 8 units
Height = 8 units
Radius = 4 units
Surface area of totally enclosed can =
2*Pi*r^2 + Pi*r*h
2*Pi*4^2 + Pi*4*8
=201.1 units^2
Hope this helps.
