here is the question
Consider the first-quadrant region R enclosed by the curves y=x2 and y=x.
(a) Find the area of R.
(b) Find the volume of the solid that is obtained when R is revolved around the x-axis.
Check your answer by redoing the problem using a different method.
(c) The centroid of R is (of course) somewhere on the line y=x. Where?
my attemb
x2=x
x2=x
x=x
x−x=0
i think 1 give zero
1−1=0
so the region is in the intevral 0≤x≤1
is it correct?
