Calculate the diameter of a circle with an area of 12.56 square centimeters

What is the formula to calculate the diameter of a circle?

Given the area of the circle is 12.56 square centimeters, what is the diameter?

Formula to calculate the diameter of a circle:

Diameter = 2 * square root of (Area / π)

Calculation:

Given Area = 12.56 square centimeters

π (pi) = 3.141

Calculate diameter: Diameter = 2 * √(12.56 / 3.141)

Diameter = 2 * √(3.9919)

Diameter ≈ 2 * 1.997974

Diameter ≈ 3.995948

Therefore, the diameter of a circle with an area of 12.56 square centimeters is approximately 3.995948 centimeters.

To calculate the diameter of a circle, you can use the formula mentioned earlier: Diameter = 2 * √(Area / π). In this case, the area given is 12.56 square centimeters, so by substituting the values into the formula and solving it step by step, we can find the diameter of the circle. Remember that the value of π is approximately 3.141. The calculation shows that the diameter of a circle with an area of 12.56 square centimeters is approximately 3.995948 centimeters. This means if you were to draw a circle with an area of 12.56 square centimeters, the diameter of that circle would be nearly 4 centimeters. Keep in mind that the diameter is a straight line passing through the center of the circle connecting two points on the circumference, and it is essential in various geometric and engineering calculations.
