Find the volume of revolution when the area B is rotated 2 pi radians about the x axis
First must recall the formula, of pi multiplied by the integral of y2
After this, the correct integration should be applied, using an appropriate method that the student has learnt
The correct limits used in definite integration, with the result being multiplied by pi as per the formula to reach the volume of the shape created.
