A solid wooden object tumed on a lathe has a length of 50 cm and diameters (measured in cm) shown in the figure. (A lalhe is a lool that spins and cuts a block of wood so that it has circular cross sections.) Use left Riemann sums to estimate the volume of the object. 50 cm 448 122 40 366 168 252 120 The approximate volume of the object is cm (Do not round until the final answer. Then round lo wo decimal places as needed.)
