If the circumference is 6, and the formula for circumference is 2πr,
r= 6/(2π) and the area is πr2 = 9
Your logic seems right, but you must have made an error somewhere, because the correct answer using your logic or mine is still 3.
area = pir2
circumference = 2pir
r = circumference/2pi
area = pi(circumference/2pi)2
area = circumference2/4pi
area = 62/4pi = 3

area from circumference area = ( circumference2 / (4 * pi) ) area = 2.865 square feet (approx)
Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Circumference = 18.85 metres Area = 28.27 square metres.
If the circumference of a circle is 6.28 then its area is about 3.138 square units
The circumference of a circle with radius of 6 is about 37.7
