Answer: 803.84 inch²

Explanation:

The lid will take the appearance of a circle so the area of the lid is the same as the area of a circle:

Area of a circle = π * radius²

The circumference of a circle is:

= π * diameter

Looking at the above, the diameter is 32inches because this is the figure to be multiplied with π = 3.14 to find the circumference.

Since diameter is 32, radius will be:

= 32 / 2

= 16 inches

Area = 3.14 * 16 * 16

= 803.84 inch²
