Answer
Area = (1.217 × 10⁹) square feet
Area = 1,216,747,566.5 square feet
Step-by-step explanation
The area of a circle is given as
Area = πr²
where
π = 3.14
r = radius of the circle = 6 km
But since the area of the circle is required in square feet, we need to convert the radius given in kilometer into feet.
1 km = 3280.84 ft.
6 km = 6 (3280.84) = 19685 ft.
r = radius of the circle = 19685 ft.
Area = πr²
Area = (3.14) (19685)²
Area = 1,216,747,566.5 square feet
Area = (1.217 × 10⁹) square feet
Hope this Helps!!!
