#Introduction to Volume of Revolution
#What is a Volume of Revolution Around the x-axis?
A solid of revolution is formed when an area bounded by a function (and other boundary equations) is rotated 2\pi
radians (360°
) around the -axis. The volume of revolution is the volume of this solid.
#Using the Disc Method
#How to Calculate a Volume of Revolution Around the x-axis?
For a continuous function , if the region bounded by:
- the curve and the -axis
- between and
is rotated 2\pi
radians (360°
) around the -axis, then the volume of revolution is:
V = \pi \int_...
