The curves are and
.
Graph the curves and
on the same graph.
Observe the graph :
\The curve intersects at and
.
The centroid of the region is .
Where and
.
The pink color represents the curve .
The green color represents the line .
Divide the region enclosed between the curve and the line into thin vertical strips of width
and length .
So the area of each strip is .
Centeriod is given by ..
The coordinate of the centeriod is
.
Substitute ,in the above equation.
.
Consider .
Consider .
Therefore, the -coordinate for the center of mass is
.
The -coordinate of the centeriod is
.
Where is centeriod of the thin vertical strip ,which is simply the midpoint if the strip.
.
Consider .
Therefore, the -coordinate of the centeriod is
.
Therefore, the centroid is
.
The centroid of the region is .
The graph of the functions of and
with the centeroid
