Just a Simple* Math Question

[naut]

Thanks for the responses.

find the equation of the line, and after that it's the integration described above.
...
Try drawing a picture of it, pictures are nice.

I did that using the 2-point formula, and it seems I got the right answer for f(y).

Picture? This is what I understand it as being (Note just realised it should be (f(y))^2 in the picture):

Equation is 3+0.1x for the line of the side of the cone.
...
pi * INTEGRAL0to5 (9 + 0.6x + 0.01x^2) dx =

Ok I got that using the 2-point formula; I also got the step before integration right. So that must mean my integration was wrong.

= pi * 635/12

I hope I got the calculation right, but I'm not sure

That's the answer.

i hope this isn't for credit

I'd be damned if it was for credit

I'm a high-school student. What's credit?

Edit:

Gah!

Seconded.
