A circular cylinder can hold 61.6 cc of water. If the height of the cylinder is 40 cm and the outer diameter is 16 mm, what is the thickness of the material of the cylinder?
(a) 0.2 mm (b) 0.3 mm (c) 1 mm (d) 2 mm

Read Solution (Total 1)

61.6=pi*r2*40;
so,r2=61.6/(pi*40);
r2=0.49;
r=0.7cm=7mm
so inner diameter is 7*2=14mm
thickness=(16-14)/2=1mm
