Answer
$i_{d}=0.300 \mathrm{~A}$
Work Step by Step
The definition of displacement current, and the formula of greatest convenience here in formula,
$$
i_d=\frac{2 \pi r B}{\mu_0}\\=\frac{2 \pi(0.0300 \mathrm{~m})\left(2.00 \times 10^{-6} \mathrm{~T}\right)}{4 \pi \times 10^{-7} \mathrm{~T} \cdot \mathrm{m} / \mathrm{A}}\\=0.300 \mathrm{~A}
$$
