Look at the circle in the figure.
The radius of the circle is .
What is its perimeter?
The radius is a straight line that extends from the center of the circle to its outer edge.
The radius is essential for calculating the circumference of the circle, according to the following formula:
If we substitute the radius we currently have, the formula will be:
2*π*2/3
Let's start solving, we'll rearrange the formula:
π*2*2/3 =
We'll multiply the fraction by the whole number:
π*(2*2)/3 =
π*4/3 =
4/3π
And that's the result!
