Final answer:
The best approximation for the area of a circle with a diameter of 19 meters is 283.4m².
Step-by-step explanation:
The formula for the area of a circle is A = πr2,
where A represents the area and
r represents the radius.
Since the diameter is given, we can find the radius by dividing the diameter by 2. I
n this case, the diameter is 19 meters,
so the radius would be 9.5 meters.
Now we can substitute this value into the formula to find the area:
A = π(9.5)^2 = π(90.25) ≈ 283.4m²
The best approximation for the area of the circle with a diameter of 19 meters is 283.4m² (Option C).
