Answer:
The formula for area of a circle is A = π r²
Explanation:
We have the diameter of the circle (8 kilometers) which gives us enough information to find the area of this cicle. We can find the radius from the dimeter (by using the simple formula r=d/2) the radius is always half of the diameter. So 8 km/2= 4 kilmeters so the radius is 4 kilometers.
now that we have the radius we can solve this problem
π×4²= 50.24
what I did was that I multiplied 3.14×4² than i got 50.24
since you want your answer in square km the answer would be 50.24²Kilometers
i hope this helps :)
happy studying!!!
