Answer: 803.84 square meters
Explanation:
Given : Derrick grows vegetables on a circular patch of land.
The radius of the patch is 16 meters.
We know that the area of a circle is given by :-

For r = 16 meters, the area of the patch of land will be :-
![\text{Area}=(3.14) (16)^2\ \ \ \ [\text{Put </strong>}\pi=3.14]\\\\\Rightarrow\text{Area}=803.84\text{ square meters}](https://img.qammunity.org/2018/formulas/mathematics/middle-school/ioxuuvmzhi0h1plsiyqkhj5llojxohnjh6.png)
Hence, the approximate area of the patch of land = 803.84 square meters.
