What would be the radius in this case?
I thought it would just be x^3, but others are saying (x^3)/2. Please help me!
If you rotate around y=0, the x axis, the outer radius is x^3, but note the rotation is only half a circle. If you do a rotational volume based on average radius, it is x^3/2. I would never do it that way, but some do.
There are a number of ways to do this.
I don’t quite understand what you mean by “based on average radius”
Dont do it that way if you don’t understand centroids.
