Question

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis.

y = 3/x

y=0
x = 1

x = 3

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis.

y = 1/(sq3x+5)

1

sq 3x + 5

y = 0

x = 0

x = 7

Answer 1

Sol" curves are given by a sxx mitocm ли x=1 X:3 Ramad y=/ We can calculate, the volume in of the solid generated by devolving the region bounded by given curves about 3-axis, using Disk" method, we can write, 3D X=1 Volume, V = TS°e de = 5° ()de =904x de 3-911 -90 (4-2- 60 [V = 60
