Math Problem Statement
Solution
The problem requires us to find the volume of the solid generated when the region bounded by the curve and the x-axis is rotated about the x-axis. This can be solved using the method of disks or washers.
Step 1: Identify the bounds
The bounds are determined by the points where the curve intersects the x-axis, i.e., where .
We solve for in the equation: Let's solve this quadratic equation to find the limits of integration.
Step 2: Set up the integral using the disk method
The volume of the solid of revolution using the disk method is given by: where and and are the x-intercepts found in Step 1.
I'll first solve the quadratic equation to find the bounds and then set up the integral. Let me proceed with that calculation now.The quadratic equation has solutions and . These are the bounds of integration.
Step 3: Set up the integral
Now, using the disk method, the volume is given by: I'll now compute this integral to find the volume.It seems like I can’t do more advanced data analysis right now. Please try again later. However, you can easily compute the volume by evaluating the integral:
You can calculate this using an integral calculator or by expanding and integrating the expression manually. If you have further questions or need assistance with any other parts, let me know!
