The inside kerb on the bend of a road is represented in figure 4. The co-ordinate values A(-46.524, 33.261) and B(5.142, 45.549) are provided in meters. The equation of the offset circle whose center is at point O' (-16.969, 24.003) is given as the following equation.
$x^2 + 33.938x + y^2 - 48.006y = 95.050$
Calculate to a precision of 1mm, the length of the arc AB, and further calculate the number of kerb stones of length 0.450 m needed along the section AB to the nearest integer.
