I provided what's given below the question. I set up the equation in the bottom. however, how do i find r hat and sin theta so that I can set up the equation to find current (I).

I provided what's given below the question. I set up the equation

C) Consider the uniform magnetic field being produced at the center of a 0.03 m in diameter coiled wire , Find the value and direction of the current in the wire that generates the magnetic field of 0.045 7 at its center . B = km Il x r sine Equation to use * 2 Km = 1x 107 diameter= 0.03m - radius= 0:015m B= 0.
