The curve fitting was not part of the problem; I just needed to find an equation for a 3d object and now I need to solve those problems using the equation.

The equation was generated by fitting a curve to a series of points.

I'm in Calc. BC and have no knowledge of those programs.

Sorry, it's 0.5. Is the rest correct and do you know how to do the other parts?

Ok, change the 10 to a 9.2 and y(4.7)=9.2 ...

Isn't it impossible to find r?

I am still stuck on this one, help greatly appreciated.

Ok, so if i want to find the volume generated by revolving the figure b/w the function and the y-axis around the y-axis from y=0 to y=9.8, y(4.7)=9.2 ...Is this correct? [(9.2)(π)(4.7)^2] - [2π*int(f(x),x,1,4.7)] Edit: Also, if I want to find the surface area of this solid, can I use the...
