A circular coil of radius $\displaystyle 10$ cm is placed in a magnetic field $\displaystyle \overrightarrow{\mathrm{B}}=(1.0 \hat{\mathrm{i}}+0.5 \hat{\mathrm{j}}) \mathrm{mT}$ such that the outward unit vector normal to the surface of the coil is $\displaystyle (0 \cdot 6 \hat{\mathrm{i}}+0 \cdot 8 \hat{\mathrm{j}})$. The magnetic flux linked with the coil is :
