12m x 3.14

C (Circumference) = Pi r (radius) 2
So, C=pi r 2
In other words. You know pi (3.14), now you need to know the radius. Divide half of the diameter (line in half of a circle) and multiply by 2. There! You have circumference!

Ans.
circumfarence of a circle=pi(d) d= dia of circle.
Given d=12m.
circumfarence of a circle= 3.14(12) = 37.68m.

Circumference of a circle is 2r(pi) or d(pi) where r is the radius and d is the diameter.
C = (12)(3.14) meters = 37.68 m

Circumference: = 2(22/7)(18/2) = 2(22/7)(9) = 396/7 or fifty six 4/7 answer: fifty six 4/7 inches section: = 22/7(18/2)² = 22/7(9)² = 22/7(80 one) = a million,782/7 or 254 4/7 answer: 254 4/7 sq. inches

C (of a circle) = (pi)R
R=D/2
= 12m / 2
= 6m
using (pi)R = C
C = (pi) 6m
= 18.84m
Circumference is 18.84m

C = π d
C = π x 12 m
C = 37.7 m (to 1 decimal place)
