I need help with these two problems please and please answer all parts and please make it legible. I've been having a lot of problems with the tutors today.

Find the arc length parameter along the given curve from the point where t= 0 by evaluating the integral s(t) = | |v(t) | dt. Then find the length of the indicated portion of the curve r(t) = 2cost i + 2sint j + 7t k, where 0 Osts . . . . . The arc length parameter along the curve, starting at t= 0 is s(t) = (Type an exact answer, using radicals as needed.)Find the arc length parameter along the curve from the point where t= 0 by evaluating the integral s = | |vidt.
