I have some integration questions for calc homework

1. Compute ds (the differential of arc length) for f(x) = 2^x .

2. Compute the arc length of f(x) = 9x ^ 2/3 over the interval [0, 1].

3. Find the surface area of the hollow shape obtained by rotating f(x) = sin(x) from x = 0 to x = π about the x-axis.

Thanks for any help!
