If you mean a circle, the circumference is diameter times pi. Pi is approximately 3.14. The area is pi times the radius squared. The radius can be found using the equation:
A = pi(r2), so
6 = 3.14(r2)
r = about 1.3824
The diameter can be found using the equation:
r = 2d, so
d = about 2.7647
The circumference can be found using the equation:
C = pi(d), so
C = 3.14(2.7647), so
C is about 8.68

Diameter:6 radius:3 circumference:6(pi) area:9(pi)
Circumference = 18.85 metres Area = 28.27 square metres.
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
Area = pi*62 Circumference = pi*12 or 2*pi*6
The circumference is 3.14 (Pi) times the diameter: 3.14 x 6 = 18.84in circumference. The area formula is: A= Pi × radius2 therefore: (3 x 3) x 3.14 = 28.26in2 area.
