If the area of a circle is [tex]64\pi[/tex], what is the circumference?

T h e a re a o f t h e c i rc l e : A O ​ = π r 2 T h e c i rc u m f ere n ce o f t h e c i rc l e : C O ​ = 2 π r =========================== A O ​ = 64 π ⇒ π r 2 = 64 π r 2 = 64 ⇒ r = 64 ​ ⇒ r = 6 C O ​ = 2 π ⋅ 8 = 16 π ​

The circumference of the circle is 16 π after determining the radius from the given area of 64 π . We used the area formula, solved for the radius, and then calculated the circumference. This showcases the relationship between area and circumference in circles.
