Result:

The circumference of a circle with area 14.5π is 23.93(*)

Formulas:

Image of Circle r = 3.81 d = 7.62 C = 23.9
C = 2·π·r
C = π·d
C = √4·π·A
π = 3.1415
A = area of the circle
C = circumference or perimeter
r = radius, d = diameter

Step-by-step Solution:

Circumference of a cicle in terms of radius:

Circumference = 2·π·r = 2·3.14·3.81 = 23.91(*)

In terms of diameter:

Circumference = π·d = 3.14·7.62 = 23.93(*)

In terms of area:

Circumference C = √4·π·A = √4·π·45.55 = 23.91(*)

(*) 23.93 centimeters exactly or limited to de precision of this calculator (13 decimal places).

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
