Answer:
[tex]4\pi[/tex] or 12.57 units
Step-by-step explanation:
It is given that the radius of a circle is 2 units.
We need to find the circumference of the circle.
The formula for circumference of a circle is
[tex]C=2\pi r[/tex]
where, r is the radius of the circle.
Substitute r=2 in the above formula.
[tex]C=2\pi (2)[/tex]
[tex]C=4\pi[/tex]
Here, [tex]\pi=\dfrac{22}{7}[/tex]
[tex]C=4(\dfrac{22}{7})[/tex]
[tex]C=\dfrac{88}{7}[/tex]
[tex]C=12.57143[/tex]
[tex]C\approx 12.57[/tex]
Therefore, the circumference of the circle is [tex]4\pi[/tex] or 12.57 units.
