The circumference is an important property of circle; it is referring as the distance around the outside of the circle. In simple words, it is the linear distance of a circle’s edge. The circumference is similar to the perimeter of a geometric figure but remembers that ‘perimeter’ is the term that is only used for polygons.
Circumference of a circle is simply evaluated by multiplying radius of the circle with 2 and π. Well, the formula for circumference can be stated as:
In this circumference equation:
If you don’t love math, then simply add the values into the above given circumference formula calculator to calculate circumference directly as it also uses the same equation for circumference.
A radius of circle is referred to as a straight line from the center of a circle to the circumference of a circle. And, if you have two or more of them, they’re said to be as radii. The plural for is radii that is pronounced as “ray-dee-eye” and remember that all radii in a circle will be the same length.
Also, sometimes the word “radius” is considered to indicate to the line itself. In contrast of that sense you may see “draw a radius of the circle”. For further detailed query, it is said to be the length of the line, and so it is referred to as the “radius of a circle that is 1.7 cm.”
And, an online radius of a circle calculator is the tool that assists you to find the radius for the given circle within a couple of seconds.
There are different formulas for radius that helps in finding the radius of the circle, these are:
If the diameter is given:
radius = D/2
If the circumference is given:
radius = C / 2π
If the area is given:
radius = √ A / π
The diameters of a circle the measurement referred to as the length of the line through the center and touching two points on its edge. The diameter is something that measures how big the circle is from rim to rim passing through the center.
Some certain times the word “diameter” is utilized to indicate the line itself. In that sense, you may notice “draw a diameter of the circle”. More specifically, it is said to be as the length of the line, and indicated as the “diameter of the circle that is 3.4 centimeters”. The diameter is also said to be as a chord.
There are different formulas for calculating diameter of the circle:
If the radius is given:
Diameter = 2R
If the circumference is given:
Diameter = C / π
If the area is given:
Diameter = √4A / π
Apart from these formulas, you simply add the value into the designated filed of the diameter of a circle calculator to find the diameter of the circle instantly.
The area of a circle is referred to as the number of square units inside that circle. Remember that if each square in the circle to the left has an area of 1 cm^2, then you could simply count the total number of squares to get the area of this circle.
The area of a circle calculator by calculator-online is also uses the same formula to find the area of a circle.
Area of a Circle, A = πr^2 square units
You can readily work out for the centroid of any N-Points, N-sided Polygon, and triangle with this help of this free calculator by calculator-online.
The surface area of a sphere is refers to exactly four times the area of a circle with the same radius. For a better understanding, you can look at the given formula of surface area of a sphere.
A sphere is referred to as a set of points in space that are a given distance r from the center. And, the volume that enclosed by a sphere is given by the mentioned formula.
V = 4/3 πr^3

All you need to enter one of these known parameters to find the remaining five values. Just enter any single value and hit the calculate button.
Once done, this circumference of a circle calculator will generate:
The values for each parameter are different as it depends on the given value.
Area of any circle can be calculated with the help of formula or circle area calculator. Different formulas will be applied in different conditions. Situation might be:
What will be the possible area of a circle if its radius is 3?
Circumference is the distance that is present around the circle and can be calculated by applying a simple formula that is: π (multiplied by) d or 2πr.
If diameter of any circle is 18 then what will be its circumference?
Also, our circumference of a circle calculator follows the same way for finding the circumference of a circle.
Distance from the midpoint to the edge of the circle represents its radius and can be measure simply by applying its formula that is: r = C / 2 x 3.14
If the circumference of any circle is 4 then what will be its radius?
Diameter divides the circle in 2 equal halves and can be calculated by means of simple formula that is: 2r.
If the radius of the circle is 2 then what will be its diameter?
Surface area of a sphere can be calculated by applying formula: 4 x 3.14 x radius of the circle. To calculate it all we have to do is to put the values in this formula. It is represented by A.
If the radius is 5 then what will be surface area of the sphere?
Sphere volume can be calculated by the formula: 4 / 3 (3.14 multiplied by r cube). While doing calculations we will put value of radius and multiply it 3 times. after that, we will do calculations according to the formula.
If the radius is 2 then what will be sphere volume?
Wondering to know how big the earth is, you are at the right spot! Well, all you need to use pi (π) to find the circumference of the Earth! Since scientists already depicted that the diameter of the Earth is 12,742km. So, get the paper and pencil to work out the circumference of the earth.
