Hence, the value of given expression is: 0.581797

Step-by-step explanation:

We know that $\dfrac{22}{7} \textradian=180degree=\pi radian$

This means

$1 \textradian=\dfrac{180 \times 7}{22}degree$

$\dfrac{16}{3} radian=(\dfrac{180 \times 16\times 7 }{22\times 3}) degree=305.577degree$

Hence, $\dfrac{16}{3}\text rad=305.577degree$

Hence, $\cos (305.577\degree)=0.581797$

Hence, the value of given expression is: 0.581797
