Verified Answer :

The area of a circle is pir^2 so 324/pi is 103 if you take the square root of that it is 10.15. so you would use the circumference formula now, which is 2 pi r so 2pi*10.15= 63.77

Answer:          

Circumference of circle is 36π feet.

Step-by-step explanation:

Given : area of circle is 324π feet²

We have to find the circumference of the given circle.

Consider Area of circle is 324π feet²

We know, Area of circle = \(\pi r^2\)

Thus, \(324\pi=\pi r^2\)

Simplify for  r , we have,

\(324=r^2\)

Taking square root both side, we have,

\(r=\sqrt{324}=18\)

Circumference of circle is given by \(2\pi r\)

Substitute, we get,

\(C=2\pi r\)

\(C=2\pi (18)=36\pi\)

Thus, Circumference of circle is 36π feet.
