  • Simpson's rule for a volume problem

    The portion ofthe graph y = tan−1 x between x = 0 and x = 1 is rotated around the y axis to form a container. The container is filled with water. Use n = 6 subintervals andSimpson's rule to approximate the work required to pump all of the water out over the side of the container. Give your answer in decimal form.(Distance is measured in meters, the density of water is 1000 kg/m3, and use 9.8 m/s2 for g.)I...

    ) A scientific instrument is encased in a diving bell which has a shape that is roughly approximated by rotating the region R around the y-axis, where R is the region under the curve y arccos(x) (in meters) over the interval [0, 1]. On its most recent trip underwater, the diving bell sprung a small leak at the top and filled up with water at a depth that was half its total height. The water has constant density a in...
