Question

Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?

Answer 1

Answer:

yo its 4.5 cm

IT IS NOT 28.3 cm

Step-by-step explanation:

Answer 2

Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

$\text{Circumference of a circle}=2\pi r$

Upon substituting the measure of circumference in above formula we will get,

$28.3=2\pi r$  

$r=\frac{28.3}{2\pi}$

$r=4.504084889500638\approx 4.5$

Therefore, the radius of circle O is 4.5 cm.
