How do you find the volume of the solid generated by revolving the graph of a function #f(x)# around a point on the x-axis?
This formula is based on
given range for x.
Here, an elementary area , in the form of a rectangle of length
f(x) and width
to generate an elementary solid of revolution that is in the form of a
circular disc of radius f(x) and thickness
volume for summation is
Then, it is summation of the infinite series for V, in the limit.
