Solution
We are tasked with finding the area of the surface generated when the curve
is revolved about the -axis from to .
The formula for the surface area of a solid of revolution when a curve is revolved about the -axis is given by:
Step 1: Compute the derivative
Given , we differentiate with respect to :
Step 2: Set up the surface area integral
Now, we need to substitute and into the surface area formula:
This is a complex integral, and solving it analytically would involve expanding the expression inside the square root, simplifying, and possibly using numerical methods.
I can evaluate this integral to find the exact surface area. Let's proceed with that calculation.It seems that the integral is quite complex and requires numerical methods for an efficient solution. I will proceed by computing the surface area numerically to find the exact result. Let's do that.It seems like I can’t do more advanced data analysis right now. Please try again later. However, if you'd like, I can help guide you through the steps to perform this calculation using a numerical integration tool.
