How do find circumference
2*pi*r
pi=3.14
r=radius of the circle
*=times
Well, if you want to find the circumference of a circle, you take the radius, multiply it by 2, and then multiply that by pi. Or as I like to call it, the never-ending dessert. So, it's like going around a circle, making two stops at the same bakery, and using pi as our currency. Just remember, the radius is like the distance from the center of the circle to the edge, and pi is like the magical ingredient that gives our circles their delicious, never-ending tastiness.
To find the circumference of a circle, you can use the formula:
Circumference = 2 * π * r
First, determine the value of π, which is approximately 3.14.
Next, find the value of the radius (r) of the circle.
Finally, multiply 2, π, and the radius (r) together to calculate the circumference.
To find the circumference of a circle, you can use the formula 2 * pi * r, where pi represents the mathematical constant pi, and r represents the radius of the circle.
1. First, determine the value of pi. Pi is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. An approximate value for pi is commonly represented as 3.14.
2. Measure the radius of the circle. The radius is the distance from the center of the circle to any point on its circumference. Make sure you measure in the same unit as the desired circumference (e.g., inches, centimeters, etc.).
3. Plug the value of pi and the radius into the formula. Multiply 2 (the number of times the radius fits into the circumference of a circle) by pi (approximately 3.14) and then multiply that result by the radius.
For example, let's say you have a circle with a radius of 5 centimeters:
Circumference = 2 * pi * radius
Circumference = 2 * 3.14 * 5
Circumference = 31.4 centimeters
Therefore, the circumference of the circle is approximately 31.4 centimeters.
