Calculate Circle Perimeter: Given Radius = 2/3 Units

Question

Look at the circle in the figure.

The radius of the circle is $\frac{2}{3}$ .

What is its perimeter?

00:00 Find the circumference of the circle

00:03 We will use the formula for calculating circle circumference

00:14 We will substitute the radius value according to the given data and solve for the circumference

00:29 And this is the solution to the question

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

$\frac{4}{3}\pi$
