Answer:
B
Step-by-step explanation:
[tex]\boxed{circumference \: of \: circle = 2\pi r}[/tex]
Since the diagram shows that the diameter of the circle is 6cm, we can find the radius by dividing it by 2.
(Diameter= 2 ×radius)
Radius
= 6 ÷2
= 3 cm
Circumference of circle
= 2(π)(3)
= 6π
= 18.8 cm (3 s.f.)
Thus, the answer is B.
