1. The problem statement, all variables and given/known data

Three small circles, C1, C2, and C3, each with radius 0.1 and centered at the origin are in the xy-, yz-, and xz-planes, respectively. The circles are oriented counterclockwise when viewed from the positive z-, x-, and y-axes, respectively. A vector field, , has circulation around C1 of $$0.02\pi$$, around C2 of $$0.7\pi$$, and around C3 of $$3\pi$$. Estimate curl at the origin.

2. Relevant equations

3. The attempt at a solution

I know that the circF for C1, C2, C3 is 2, 70, and 300 respectively.. how do I get the curl if I know the circF for each of those
