For an example we have an area of 303000 square meters. Determine the diameter of a circle given that the area is 125 cm 2. If the diameter is given we can find the radius by dividing the value of diameter by 2.
Yet with just the diameter or half the diameter the radius or even only the circumference the distance around you can calculate the area of any circle. Now double the radius to get the diameter Example. The procedure is reversed to calculate the area of a circle from its diameter.
If you only know the area of the circle use the formula diameter 2 x areaπ. A PI r 2. Therefore Radius 2 Area.
C 2 PI r. So here instead of area were asked to find the arc length of the partial circle and thats we have here in this bluish color right over here find this arc length. Enter the area contained within a circle.
The calculations are done live. After getting the radius we can substitute its value in the formula. It is interesting to compare the area of a circle to a square.
This tool will calculate the diameter of a circle from the area and will convert different measurement units for area and diameter. It is a part of the circumference of the circle. The Diameter goes straight across the circle through the center.
In most cases you can use the simple formula Api r2. Square centimeters results may be rounded Area of a Circle Formula. For example if your circle has a circumference of 23 inches the diameter would be 23π or approximately 732 inches.
Sector of a circle. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle or any two points on the circle as long as they are exactly 180 degrees apart. The diameter is twice the radius or d 2r.
Divide the area in square units by Pi approximately 314159. The equation of a circle includes the radius and it is given by. C circumference of the circle.
