Answer:
Step-by-step Step-by-step explanation:
It's given that, Radius of the circle is 9 cm.
We know that Circumference of the circle is calculated as 2πr
where,
Substituting the required values,
Circumference = 2 × 3.14 × 9
= 6.28 × 9
= 56.52 cm
Hence the required circumference of the circle is 56.52 cm
