Answer:
1,216,747,567 square feet.
Step-by-step explanation:
The area of a circle can be calculated as:
Where π is 3.14 and r is the radius of the circle.
Since we need the answer in square feet, we first will convert 6 km to ft. So, if 1 km is equivalent to 3280.84 ft, we get:
Therefore, replacing π is 3.14 and r by 19685 ft, we get that the area of the circle is equal to:
So, the answer is:
1,216,747,567 square feet.
