Question

Find the circumference of a circle with an area of 28.26. Show work please.

Answer 1

Answer:

18.84

Step-by-step explanation:

Since the formula for circumference is $C=2\pi r$, we need to first find the radius. The formula for the radius is $r=\frac{\sqrt{A\pi } }{\pi }$, so we will get $r=3$. Substitute that into $C=2\pi r$, and we get $C=18.84$. Hope this helps!
