Magnetic field in the center of the toroid

JasonBourneV

Can't this be calculated from B = mu*N*I/2*pi*r? Book explanation says that this can't be done because there is "no path through the center along which the field is constant" So I guess I must use the Biot-Savart Law. How should I go about doing that?
