Divide the area (in square units) by Pi (approximately 3.14159). Example: 303,000/3.14159 = 96447.98 ... Now double the radius to get the diameter (Example: 621.12 meters). ... Diameter units:

Area =πr²(θ/360) = 3.14 * 3² * (30/360) = 3.14 * 9 * 0.083 = 2.35. The above example will clearly illustrates how to calculate the Area, Diameter and Circumference of a Circle,

Online area calculator. ... The Radius of a circle is the distance from the center of the circle to the outside edge. Thus the diameter of the circle is twice the size of the radius of a circle.

pi ( ): A number, 3.141592..., equal to (the circumference) / (the diameter) of any circle. radius: distance from center of circle to any point on it.

Definition: A circle is the locus of all points equidistant from a central point. ... diameter: the longest distance from one end of a circle to the other.

The distance around a circle is called the circumference. The distance across a circle through the center is called the diameter. is the ratio of the circumference of a circle to the diameter.

We use the Greek letter (pronounced Pi) to represent the ratio of the circumference of a circle to the diameter. ... Use = 3.14 to calculate your answers.

* Draw a square inside the circle. Calculate the area of the square. * Estimate the area of the circle by relating it ... Expected responses: The circumference of a circle is 3.14 times its diameter.

Calculate the volume, surface area, circumference, diameter and radius of a sphere from any starting point e.g. if you know the volume you can derive the radius. ... Circle Area = π r2
