When we are asked to calculate the area of a circle with a given circumference, we are essentially finding the amount of space enclosed within the circle. The circumference is the distance around the circle, while the area is the measure of the surface inside the circle.
The area of a circle with a circumference of 56.52 units is approximately 160.01 square units.
List the formulas for calculating the area and radius of a circle:
Plug the radius of the circle into the formula:
Finally, calculate the area using the formula: A = π * r^2
Express the answer in numbers.
List the formulas for calculating the area and diameter of a circle:
Plug the diameter of the circle into the formula:
Calculate the radius by dividing the diameter by 2: r = d / 2
Finally, calculate the area using the formula: A = π * r^2
Express the answer in numbers.
List the formulas for calculating the area and circumference of a circle:
Plug the circumference of the circle into the formula:
Finally, calculate the area using the formula: A = (C^2) / (4 * π)
Express the answer in numbers.
Calculate the radius using the formula: r = 56.52 / (2 * π)
Calculate the area using the formula: A = π * r^2
Round the answer to the appropriate number of decimal places:
Therefore, the area of a circle with a circumference of 56.52 units is approximately 254.47 square units.
A circle is a two-dimensional geometric shape that is perfectly round and consists of all points in a plane that are equidistant from a fixed center point. It is defined by its radius, diameter, and circumference.
To draw a circle, you need a compass, which is a tool with two arms. Place the sharp end of the compass at the center point of the circle and rotate the other arm around it, creating a perfect circle.
A circle has several important measurements:
The symbol Π (pi) represents the mathematical constant that is the ratio of a circle's circumference to its diameter. It is an irrational number, approximately equal to 3.14159, but it can be rounded to 3.14 for most calculations.
The origin of the symbol Π (pi) can be traced back to ancient Greek mathematicians. It was first introduced by the mathematician William Jones in 1706 and later popularized by the Swiss mathematician Leonhard Euler in the 18th century.
