Answer:
A = 4 pi km ^2
or approximately
A = 12.56 km^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
The radius is 2
A = pi *2^2
A = 4 pi km ^2
If we approximate pi as 3.14
A = 4 * 3.14
A = 12.56 km^2
Answer:12.57km
Step-by-step explanation:
A=π·r^2=π·2^2≈12.56637
or just radius squared multiplied by pi
