Letter B only
A. Let R be the region bounded by y=3* –1 , y= 0, and x=2. Set-up only the definite
integral that will yield the following:
1. Volume of the solid generated when R is revolved about
a. the x-axis using
i. vertical strips
eq1
ii horizontal strips
b. у-
using x as the variable of integration
B. Set-up the integral that will find the following
a. centroid of the region R
b. centroid of the solid generated by revolving R about the line x= 3.
c. centroid of the solid generated by revolving R about the line y = 8.
C. Set-up the definite integral to find the length of the arc of the graph of y = Vx-1 from
x = 2 to x= 5.
D. Set-up the definite integral that will give the area of the surface generated by revolving
the arc y=2* from x=0 to x=2.
a. about x=2 using x as a variable of integration
b. about y = 5 using x as the variable of integration
E. The length of a rod is 4ft and the linear density at the center is 2 kg/ft. The measure
of the linear density at a point on the rod varies directly as the third power of the
measure of the distance of that point from the left end of the rod. Set-up the definite
integral that will give the center of the rod.
