Answer:
C = 28.278 m
Step-by-step explanation:
The attached figure shows a circle whose diameter is 9 m.
Radius = Diameter/2
r = 9/2 = 4.5 m
The circumferance of the circle is given by :
C = 2πr
Put r = 4.5 m in the above formula
C = 2 × 3.142 × 4.5
= 28.278 m
So, the circumference of this circle is 28.278 m.
