							Sol. Given that, for the cylinder
Length = l = 4.54 cm, radius = r = 1.75 cm
Volume = πr2l = πr2 (4.54) x (1.75)2
Since, the minimum no.of significant digits on a particular term is 3, the result should have
3 significant digits and others rounded off.
So, volume V = πr2l = (3.14) x (1.75) x (1.75) x (4.54) = 43.6577 cm3
Since, it is to be rounded off to 3 significant digits, V = 43.7 cm3
