**Title: Understanding Volume of Solids of Revolution** **Description:** This illustration demonstrates how to calculate the volume of a 3D solid obtained by rotating a 2D shape about an axis. **Diagram Explanation:** - **Axes:** The diagram displays a standard Cartesian coordinate system with the x-axis and y-axis marked. The x-axis includes numbers at positions 5 and 8. The y-axis includes numbers at positions 3 and 7. - **Shape:** A right triangle is situated between x=5 and x=8 and extends vertically from y=3 to y=7. The triangle is shaded for emphasis. The right angle of the triangle is at the point (5,3). - **Rotation Indication:** There is an arrow curving around the x-axis, illustrating the direction of rotation to form the 3D solid. **Objective:** By rotating the triangular area around the x-axis, a three-dimensional solid of revolution is created. Calculating the volume of this solid involves using integral calculus, specifically the disk or washer method, depending on the orientation and bounds given in a mathematical problem. Understanding this concept is crucial for applications in physics, engineering, and various fields where modeling and design require volumetric analysis of objects.
