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).
(a) Suppose C(r) = a + br^3 C(2) = a + b*2^3 = a + 8b = 124 ..... (1) C(3) = a + b*3^3 = a + 27b = 181 ..... (2) (2) - (1) , we have 19b = 57 , so b = 3 , substitute into (1) a = 124 - 8b = 124 - 8*3 = 100 , hence : C(r) = 100 + 3*r^3 C(5) = 100 + 3*5^3 = 475 (b) By (a) , outer radius = 5...
