Best ResponseYou've already chosen the best response.1yes that length in terms of x (imagine it sliding back and forth between x = 0 and x = 3)

Best ResponseYou've already chosen the best response.0Well it would change depending on what x is in the function y=x^2

Best ResponseYou've already chosen the best response.1it's simply x^2, right?

Best ResponseYou've already chosen the best response.1whatever x is, the vertical distance from the curve to the x axis is x^2 units

Best ResponseYou've already chosen the best response.1imagine cutting it up into infinitely many disks that are infinitesimally small then glue those pieces together to form this 3D shape this is effectively what you are doing when you evaluate \[\Large \pi\int_{a}^{b}(R)^2dx\] \[\Large \pi\int_{0}^{3}(x^2)^2dx\] \[\Large \pi\int_{0}^{3}(x^4)dx\]
