A circle with a radius of 4 miles has a circumference of 25.13 miles.
A circle with a radius of seven miles has an area of ~153.938 square miles.
Radius = 4.068 miles (to 3 dp)
It is the circle reaching out for 62.8 miles from the centre.
It is the circle reaching out for 62.8 miles from the centre.
Circumference = 34*pi miles

Radius = 4.068 miles (to 3 dp)
If the area is a circle and the radius of the circle is 21 miles, the distance around the circle (circumference) is 131.95 miles. The area of that circle is 1,385.4 square miles.
It is the circle reaching out for 62.8 miles from the centre.
It is the circle reaching out for 62.8 miles from the centre.
The radius of a circle with an area of 1,808.64 square miles is: about 24 miles (23.994 miles).
Radius is the square root of 1808.64/pi = about 24 miles
The radius is 1.261 miles.
A circle with a radius of 11.5 miles has an area of 415.48 square 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
