Circumference of a circle: 2 x pi x radius.
The circumference, C, of a circle is given by the formula
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
(pi)D
C=Pi x diameter
diameter = circumference/pi (pi = 3.14159265 or 3.14 for rough approximation).
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
The circumference, C, of a circle is given by the formula
Circumference = (diameter) multiplied by (pi)
Circumference of a circle = (pi) x (diameter)
To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi
(pi)D
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. Given a circumference of 84 units, you can plug this value into the formula and solve for the diameter. Dividing 84 by π gives you approximately 26.67 units as the diameter of the circle.
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
C=Pi x diameter
It is not clear whether you want the formula of some aspect (area or circumference) of a circle when given its radius or a formula for its radius when given some characteristic measure of the circle.
diameter = circumference/pi (pi = 3.14159265 or 3.14 for rough approximation).
To find the radius of a circle when given the circumference, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 132 cm, you can plug this value into the formula: 132 = 2πr. To solve for the radius, divide both sides by 2π: r = 132 / (2π) ≈ 21 cm. Therefore, the radius of the circle is approximately 21 centimeters.
