Magnetic flux:

$\overline{){{\mathbf{\varphi }}}_{{\mathbf{B}}}{\mathbf{=}}{\mathbf{B}}{\mathbf{A}}{\mathbf{c}}{\mathbf{o}}{\mathbf{s}}{\mathbf{\theta }}}$, where B is the magnetic field, A is the area, and θ is the angle between B and A.

Area of a circular loop:

$\overline{){\mathbf{A}}{\mathbf{=}}{{\mathbf{\pi r}}}^{{\mathbf{2}}}}$, where r is the radius of the circular loop.

The diameter of the circular loop is 16cm

Therefore, radius, r = 16/2 = 8 cm = 0.08 m
