I need help with this problem please, and please make it legible.

l 1|: Find the arc length parameter along the given curve from the point where t = 0 by evaluating the integral s(t) = I|v(1:)| dz. Then nd the length of the indicated portion of the curve r(t) = 7cost i + 7sin t j + 6t k, where 0 5 ts El 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 1|: as needed.)
