If c is the curve given by =(1++(1++(1+(t)=(1+3sin⁡t)i+(1+3sin 2⁡t)j+(1+2sin3⁡t)k, 0≤≤≤t≤π2 and f is the radial vector field ,y, z)=++(x, y,z)=xi+yj+zk, compute the work done by f on a particle moving along c.

Both the red and blue line segments stretch from the center of the circle to a point on the circle. the length of the blue segment is 5. how long is the red line segment?
