ind the arc length parameter along the given curve from the point where t = 0 by evaluating the integral s(t) = v(x)] dr. Then find the length of the indicated portion of the curve r(t) = 8cost i + 8sin tj + 3t k, where 0 sts 2 The arc length parameter along the curve, starting at t=0 is s(t) = Type an exact answer, using radicals as needed.) The length of the indicated portion of the curve is L = Type an exact answer, using radicals and as needed.)
