Circumference = 2 x pi x radius
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
The formula for the circumference of a circle is pi * diameter or (2 radius.)
Divide the circumference by 2*pi because 2*pi*radius = circumference
this is called finding the circumference. The formula is 2*pie*radius
pi x 2r
Divide by 3.14 then by 2
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
Formula for finding the circumference of a circle: 2 multiplied by pi multiplied by radius
circumference of a circle = 2*pi*radius or pi*diameter
The circumference of a circle with a radius of 6.74 inches is approximately 42.34 inches. The circumference of a circle is found using the circumference formula: Circumference = 2 * π * radius So, all you have to do is plug in the radius into the formula, and approximate π to be 3.14159.
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
To find the radius of a circle with a circumference of 121, 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 121, you can plug this value into the formula and solve for the radius. Dividing 121 by 2π will give you the radius of the circle, which is approximately 19.24 units.
