Applications of Integration : Exercise 2
Introduction
Exercise 2 on integration, will focus on, applying integration to find the volume of bounded region.
Exercise 2 on integration, will focus on, applying integration to find the volume of bounded region.
- The finite region bounded by the curve with the equation y = 8x – x2 and rotated through 360° about the x axis. Using integration find, in terms of Ï€, find the volume of its solid form.
- A solid is formed by rotating the part of the graph of y = 2x2 between x = 1 and x = 2 through 360° about the x-axis. Find the volume of the solid.
- Find the volume generated by revolving the region bounded by y = x2 + 2, y = 1, x = 0 and x = 2 about the x-axis.
- Calculate, in terms of Ï€, the volume generated by revolving the region through 360° about the y-axis.
- Figure below shows the curve y = 9x -x2 which intersects a straight line at point (3, 0) and point M. Calculate
a) the coordinates of M
b) the area of the shaded region
c) the volume generated, in terms of π,
when the region bounded by the curve, the y-axis and the straight line is revolved through 360° about the y-axis.
