Absolute error of the thickness of 500 pieces = 48mm × 1/240 = 0.2mm The thickness of each piece = (48±0,2mm) ÷ 500 = 0.096±0.0004mm ∴ The possible range of x is 0.0956～0.0964 (mm).

Thickness of the glass = (10 - 9)/2 = 0.5 cm Volume of the material used = Volume of the big cylinder - Volume of the small cylinder = piR^2H - pir^2h = pi[(10/2)^2(20)] - pi[(9/2)^2(20 - 0.5)] = (841pi/8) cm^3
(1)Find (i)the maximum error of the thickness of a piece of paper As the thickness for 500 pieces is correct...0.5/500 = 0.001 mm (ii)the thickness of each piece of paper 58/500 = 0.116 so the thickness of each piece of paper is 0.116mm (iii)the percentage error,correct to the ...
