Recall the formulae for arc length, L and surface area, S. "b L = = 1 + 1/(x) dx a S= = [" 27/ (x) /1 + (r^(x)) dx (a) Use the arc length formula to find the length of the curve y=mx+b along x = 0 to x = c. Note: if you solution does not include the use of the arc length formula, you will not receive any credit. (b) Set up, but do not evaluate, the integrals that gives the surface area of the object generated by the curve x=y +2y along y = 0 to y = 5 rotated around the y-axis.
