If the radius of a circle is given in 'r' units then it is easy to determine the diameter formula as given below: What Is the Diameter Formula When Radius of a Circle Is Known? If the area of a circle is given in square units then it is easy to derive the diameter formula as given below: This means the radius is half of the value of the diameter.įAQs on Diameter Formula What Is the Diameter Formula When Area of a Circle Is Known? We know that diameter is twice the value of the radius. We will use the diameter formula of the circle when the circumference is given.ĭiameter formula = Circumference/π = 8 unitsĪnswer: The diameter of the given circle is 8 units.Įxample 3: Using the diameter formula, can you determine the value of the radius if the diameter of a circle is 12 units? We will use the first formula to find the diameter of the circle.Īnswer: Diameter of the given circle = 48 inches.Įxample 2: Find the diameter of a circle whose circumference is 8π units. Let us solve some interesting problems using the diameter formula.Įxample1: Using the diameter formula find the diameter of a circle whose radius is 24 inches long.

Diameter Formula Using Radius of a Circleįormula 1: The diameter is twice the length of the radius.ĭiameter Formula = 2 × Radius Diameter Formula Using Circumference of a Circleįormula 2: The diameter is the ratio of circumference to π.ĭiameter Formula = Circumference ÷ π Diameter Formula Using Area of Circleįormula 3: We can derive the diameter formula using the area formula which is We can find the diameter of a circle when the radius, area, or circumference is known. Let us consider the different cases of the Diameter Formula. Since there are infinite points on its circumference, this means that a circle has an infinite number of diameters and each diameter of the circle has an equal length. The straight line connecting a point from one end of the circle to a point on the other end of the circle and passing through the center is called a diameter. Diameter is one of the important parts of a circle.

Multiply the diameter by π (pi is approximately 3.14).Before we begin with the diameter formula, let us recall what is a diameter. It is done, you found the circumference of the circle.Ĭalculate the circumference of a circle with the diameter Then, multiply the result by π (pi is approximately 3.14).

How to find the circumference of a circle?Ĭalculate the circumference of a circle with the radiusįirst, multiply the radius by 2 to get the diameter. The circumference of a circle is the length of the curve that encloses that circle. It is like the perimeter of other shapes like squares. A circle's outside boundary is called the circumference.

The circumference of a circle is the distance around the outside of the circle. The circumference of a circle is the length of the curve that encloses that circle.Ī disc (also spelled disk) is the region in a plane bounded by a circle.Ī disc with center O and radius r is the surface bounded by the circle with center O and radius r. The perimeter is defined as the circumference of the circle. The diameter is the distance from one point on a circle through the center to another point on the circle.

The diameter is defined as twice the length of the radius of a circle. The radius of a circle is the length of the line from the center to any point on its edge. The perimeter of a circle is calculated using the formula 2 x Pi x Radius, or Pi x Diameter. It is noted 'r'.ĭiameter is a line segment, having boundary points of circles as the endpoints and passing through the center. Radius is the fixed distance between the center and the set of points. When a set of all points that are at a fixed distance from a fixed point are joined then the geometrical figure obtained is called circle. Perimeter P of the circle = 2 x π x r ≈ 2 x 3.14 x 3 ≈ 18.84 cm²Ĭalculate the perimeter of a circle RadiusĪ circle is a closed shape formed by tracing a point that moves in a plane such that its distance from a given point is constant. With π (number pi) approximately equal to 3.14
