3. A particle has a smooth, circular cross section of diameter d p . The fractal dimension of the particle's perimeter is to be estimated by fitting a four-sided and a six-sided regular inscribed polygon to the circle. Based only on this information, what fractal dimension is estimated for this step size range. [Hint: The length b of the side of a regular inscribed polygon with n sides is b = d p × sin(180 o /n).] (15%) Sol>
