It is the circle reaching out for 62.8 miles from the centre.
A circle with a radius of 4 miles has a circumference of 25.13 miles.
Radius = 4.068 miles (to 3 dp)
3,963.1676 miles
A circle with a radius of seven miles has an area of ~153.938 square miles.
A sphere with a radius of 4.4 miles has a volume of 356.82 cubic miles.
The moons average radius in miles is 1079 miles.
The Earth's radius is approximately 6,371 kilometers and 3,959 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
The radius of the sun = 695,500 kilometers or 432,163.664 miles.
A circle with a radius of 4 miles has a circumference of 25.13 miles.
The radius of a circle with an area of 1,808.64 square miles is: about 24 miles (23.994 miles).
radius = 251.57 divided by 2*pi = 40.03860903 miles
Radius = 4.068 miles (to 3 dp)
3,963.1676 miles
A circle with a radius of seven miles has an area of ~153.938 square miles.
A sphere with a radius of 4.4 miles has a volume of 356.82 cubic miles.
The radius of a circle is half its diameter or, in this case, half the distance across the circle. Since 5.8 miles refers to the diameter, the radius would be half of that, which is 2.9 miles.
