Hat it has circular cross sections.) use left riemann sums to estimate the volume of the object. a wooden object of length 50 centimeters that has circular cross sections is turned on a lathe. a curve follows seven plotted points that are evenly spaced on the top of the wooden object, where a plotted point is at each end of the object. from left to right, the diameters of the cross sections at the plotted points are labeled as follows: 12.8, 14.0, 16.6, 25.4, 36.4, 42.0, 44.8. 12.8 44.8 42.0 36.4 25.4 16.6 12.8 14.0 50 cm 50 cm the approximate volume of the object is 41734.4941734.49 cmcubed3. (do not round until the final answer. then round to two decimal places as needed.)
