Answer
$4.7\times10^{-11}F$
Work Step by Step
Find the capacitance using equation 17–9, the capacitance of a parallel-plate capacitor with a dielectric.
$$C=\kappa\epsilon_o \frac{A}{d}$$
$$C=(2.2) (8.85\times10^{-12}C^2/(N\cdot m^2))\frac{(6.6\times10^{-2}m)^2}{1.8\times10^{-3}m}$$
$$=4.7\times10^{-11}F$$
