Thank you Ms. Sue. Sorry I didn't tell you we're just learning that pi=3 for now. It made everything complicated for you to check if my answers were correct. :P
But what is this formula usually used for?Diameter=Circumference/π?
Is it used to find the diameter of something?
That's ok. I'm glad we've straightened out that problem.
The formula is usually written as
Circumference = pi * diameter
But if we want to find the diameter, we can switch it around to
Diameter=Circumference/π
And the formula Radius=Circumference/2π
is that used to find the radius? And is it
usually written as Circumference=2πr?
Yes.
Okay, thank you again! :D
No problem! I'll be happy to explain.
The formula you mentioned, Diameter = Circumference / π, is used to find the diameter of a circle when you know its circumference. The diameter is the distance across a circle, passing through the center, and it is one of the fundamental measurements used to describe a circle.
The formula can be rearranged to find the circumference when you know the diameter: Circumference = π * Diameter. This formula is frequently used in geometry and engineering to calculate various properties of circles and circular objects.
For example, if you have a circular object and you know its circumference, you can use this formula to find its diameter. Conversely, if you know the diameter, you can use the formula to calculate the circumference. This relationship between the diameter and circumference of a circle is a fundamental concept in geometry and is represented by the constant π (pi).
