A circ ular cylinder can hold 61.6 cc of water. If t he height of the cylinder is 40 c m and the
outer diameter is 16 mm, what is the thicknes s of t he mat erial of the c ylinder?
(a) 0.2 mm (b) 0.3 mm (c) 1 mm (d) 2 mm

• circular cylinder volume is given...61.6cc=pi*(inner radius)2*h
  
  note all units in above equation are in centimeters
  
  now solving the equation you get inner radius=0.7 cm=7mm
  
  thus thickness= (outer dia/2)-inner radius= 8-7=1 mm
