Look at the circle in the figure.
The radius of the circle is .
What is its perimeter?
Step-by-step solution
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, which can be found using the following formula:
If we substitute in the radius we have, the formula will be:
2*π*2/3
To solve this, first we'll rearrange the formula like so:
π*2*2/3 =
We'll then multiply the fraction by the whole number:
π*(2*2)/3 =
π*4/3 =
4/3π
