Question

Suppose the radius of a circle is 8 units. what is its circumference​

Answer 1

Answer:

$\large\boxed{C=16\pi\approx50.24}$

Step-by-step explanation:

The formula of a circumference of a circle:

$C=2\pi r$

r - radius

We have r = 8. Substitute:

$C=2\pi(8)=16\pi$

$\pi\approx3.14\to C\approx(16)(3.14)=50.24$
