Best Answer

The area of a circle can be worked out by the formula πr2 , where r is the radius of the circle and π (pi) is the ratio of the circumference to the diameter (= 3.142 to three decimal places)

So 3.142 × 122 = 3.142 × 144 = 452.4 square miles

There are 640 acres in one square mile, so 640 × 452.4 = 289,530 acres

In a circle of six miles radius, the area covered is 289,530 acres.

What Circle on Earth's surface has the center of Earth as its center?

Any circle on the Earth's surface whose center is at the center of the Earth is called a "great circle". Any circle with its center anywhere else is called a "small circle". Spiritually, many consider the kaaba (Mecca) to be the center of the Earth's surface.

What is called a great circle?

A great circle is any circle on the surface of a sphere whose center is at the center of the sphere. The shortest distance between two points on the surface of a sphere is a part of the great circle that passes through them.

What does radius mean in geometry?

The radius is any point on the surface of the circle to the center of the circle.

Is the moon a perfect circle?

No , not with the surface being with so many craters .

Why is the value of acceleration due to gravity varies from place to place on the surface of the earth?

Because the earth is not a perfect circle or perfect sphere. So at the poles, the force of gravity is ls different from that from the center of the earth.

How do you determine latitude?

Think of the Earth as a circle with a center. The flat circle is made by the Equator. From the center you draw a line intersecting the surface of the earth you're measuring. And then you measure the angle the line from the center of the earth to that surface makes with the flat circle. And there you have your latitude :)

In soccer what is the area of the center circle?

diameter of a soccer center circle is 10 meters. means the radius is 5 meters. area of a circle is (pi)*(r)squared. approximately 78.5398.

What is the difference between a circle and a sphere?

A circle is two dimensional; a sphere is three dimensionalAnswerA circle is a simple shape consisting of points in a plane (flat surface) which are equidistant from a given point called the center. A sphere is a perfectly round geometrical object in three-dimensional space, such as the shape of a round ball. Like a circle in three dimensions, a perfect sphere is completely symmetrical around its center, with all points on the surface lying the same distance r from the center point.

A round figure whoes surface is at all points equidistant from the center?

A circle

What shape has no verticles and no corners and not all points on its surface are equidistant to its center?

a circle

Why is the great circle important?

A great circle is a circle on the surface of a sphere whose center is at the center of the sphere. The shortest distance between two points on the surface of a sphere (like the Earth for example) is the piece of the great circle that joins them. If you're flying, then that's the route you want to follow.

Does every great circle of a sphere have to pass through its center?

Let's be very careful here: The "great circle" of a sphere is a circle that lies on the surface ofthe sphere, so there's no way the great circle can "pass through" the sphere's center.However, in order for the circle to be a "great circle", its center must be the center of the sphere.
