Hi. I hope I can help you with this question.
The formula for circumference is pi times the diameter :
C = pi * d
Since pi is already known, as well as the circumference. You can solve for d.
Now you have the circle's diameter. Half of that is its radius.
The area of a circle is as followed:
A = pi * (radius)^2
since you know pi, and you now know the radius, i'm pretty sure you can finish it out. Hope this helped. Peace.
if the circumference of a circle is 16 meters,what is the approximate area of the circle

C = pi * d
16 = 3.14 * d
16/3.14 = 5.0955
5.0955 / 2 = 2.5478
Use 2.5478 for the radius and the formula I posted to your last question to find the area.
