How to Calculate the Diameter of a Circle from Its Area

Learn how to determine the diameter of a circle using its area with a simple formula.

308 views

To find the diameter of a circle given the area, use the formula: `Diameter = 2 sqrt(Area / pi)`. First, divide the area by pi (approximately 3.14159). Then, take the square root of the result. Finally, multiply by 2. For example, if the area is 50 square units, the diameter is `2 sqrt(50 / pi)`, which equals approximately 7.98 units.

FAQs & Answers

  1. What is the formula to find the diameter of a circle from its area? The formula is Diameter = 2 * sqrt(Area / pi).
  2. How do I calculate the area of a circle? The area of a circle is calculated using the formula Area = pi * (radius^2).
  3. Why is pi important in circle calculations? Pi is the ratio of a circle's circumference to its diameter, and it is essential in calculating all aspects of circles.
  4. What does the diameter of a circle represent? The diameter is the longest distance across the circle, passing through the center, and is twice the length of the radius.
