A circle with a mile radius has an area of pi sq miles.
It is 502655 sq miles, approx.
There are pi*r^2 = 2827 square miles, approx.
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
A circle that encloses 1,100 square miles of area has a radius of 18.712 miles .
This is the area of a circle with a radius of 100 miles →area = π × radius² = π × (100 miles)² = 10,000π sq miles ≈ 31416 sq miles
Area of a circle = pi R2 = 9 pi = 28.27 square miles (rounded)
Area of a circle = pi R2 = 16 pi = 50.265 square miles (rounded)
