Circle Calculator: Different Formulas used by the Calculator and how to find the Radius
The AllCalculator.net Circle Calculator calculates a given circle’s Area, circumference, radius, and diameter. However, input values like Area, radius, and diameter are input in the Circle Calculator. The Calculator will calculate the values for the other unknown variables/units.
The Circle Formulas
Radius and Diameter.
r = d/2
d = 2r
Area Formula
A = πr2 = πd2/4
Circumference Formula
C = 2πr = πd
Using the above formula, find the Area, circumference, diameter and radius using the Circle Calculator. So by any given variable, calculate the values and properties of a Circle.
Calculate A, C and d
Let’s assume the value of r is given. Input the n values of A, C and d in the Calculator.
A=πr2
C=2πr
d=2r
Calculate r, C and d
Let’s assume the Area of a circle is given. Input the values of r, C and d in the equation
r=√A/π
C=2πr=2π√A/π
d=2r=2√A/π
To calculate A, r and d
Let’s assume here circumference of CircleCircle is given. So calculate the Area, diameter and radius of the Circle.
r=C/2π
A=πr2=π(C/2π)2=πC²/4π²=C²/4π
d=2πr=2C/2π=C/π
To calculate A, C and r
Let’s assume the diameter is provided. So the formula is the circumference of a circle. Put the values of A, C and r
r=d/2
A=πr² =π(d/2)²=πd²/4
C=2πr=2πd/2=πd
These were some ways to capture the part of a circle using the formula.
However, these can be automatically calculated by the AllCalculator.nwt Circle Calculator given one input value.
What is the radius of a circle?
To evaluate the radius of a circle from the circumference or diameter and Area of a circle. The concept and method are quite easy. There are some formulas, or one can use the Circle as a calculator.
So a circle is a two-dimensional shape consisting of various points. These points lie at the same fixed distance. This distance is known as the radius of the Circle.
To find the radius of a circle. There are three formulas.
From the Area.
r=√A/π
From the circumference
r=C/(2×π)
From the diameter of the Circle.
r=d/2
The radius of a circle is considered from all the above equations.
Conclusion.
Circle Calculator can determine the value of radius and diameter. Circumference and Area of a circle.
