Homework Help: Calculus

Posted by Paul on Wednesday, August 8, 2012 at 1:18pm.

This is a question from my textbook that does't have a solution and quite frankly I have no idea what to do. Any tips would be greatly appreciated.

Given the function f defined by f(x) = 9 - x^2. Find the surface area bounded by the curve y = f(x), the x axis and the lines x = 2 and x = 0.

(a) Find the Riemann Sn sum algebraically, obtained by cutting the surface in n intervals of equal width and considering circumscribed rectangles


(b)Evaluate the surface area by finding lim n->infinite Sn

Thank you
