The diameter of the lid is d= 4.4 in.

The formula for the area of circular lid is,


A=(\pi(d)^2)/(4)

Substitute the values in the formula to obtain the area of lid.


\begin{gathered} A=(\pi\cdot(4.4)^2)/(4) \\ =(3.14\cdot19.36)/(4) \\ =3.14\cdot4.84 \\ =15.1976 \\ \approx15.20 \end{gathered}

Thus area of lid is 15.20 square inches.
