Answer:
22.34 km²
Step-by-step explanation:
Here we have a circle whose diameter is 5 1/3 km. As an improper fraction, that's 16/3 km. Half that, or 8/3 km, is the radius.
The area of a circle is A = πr², where r is the radius.
In this case, the area is A = π(8/3 km)², or (64/9)π km², or 22.34 km² (same as first answer choice).
