Answer: 39.4 m^2

Explanation:
The area of a circle is pi * radius squared. The diameter is 4 m, the radius is half the diameter so for the equation the radius is 2 m.

Pi times 2 is 6.28 (remember that pi is roughly 3.14), then square that sum of 6.28.

6.28^2= 39.4384

The answer is 39.44 but the answer must be rounded to the nearest tenth, 39.4384 is 39.4 rounded to the nearest tenth.
