Math Forum / Mathematics / Recreational Math / July 2009Parabola calculations
Find (i) the volume swept out by revolving the area bounded by the parabola y = 2x^2 and the line y = 2 about the y axis; (ii) the length of the arc bounding this area; (iii) the area swept out by this arc when it is revolved around 0y. Hi Peter, You are right again. These three math questions were from an old text book that I used in my youth, whilst studying for my professional engineer's degree.I am quite rusty now-a-days, but like to keep the brain working. Regards Bill. |
