Answer:
The area of the circle is [tex]1\pi[/tex] or approximately 3.14 [tex]km^2[/tex]
Step-by-step explanation:
The formula to find the area of a circle is [tex]\pi r^2[/tex], where [tex]r[/tex] represents the radius of the circle. In this case, the area would be [tex]1^2*\pi[/tex] = [tex]\pi[/tex] ≈ 3.14 [tex]km^2[/tex].
