Compute the average temperature of a wire in the shape of

Question

1. Compute the average temperature of a wire in the shape of the helix r(t) = (cos(t), t/10, sin(t)), 0 ≤ t ≤ 10π,if the temperature at the point (x,y,z) on the wire is given by T(x,y,z) = x² + y + z².

2. Use a line integral to compute the area of the part of the surface y = sin(x), 0 ≤ x ≤ π/2, above the xy-plane and below the surface z = sin(x) cos(x).
