Answer:
C = 18 pi cm or approximately 56.52 cm
Step-by-step explanation:
The circumference is given by
C = 2* pi*r
C = 2 * pi*9
C = 18 pi
Using 3.14 as an approximation for pi
C = 18*3.14
C =56.52
Answer: 56.52
Step-by-step explanation:
In order to find the circumstance, we will need to use this formula:
2πr
(2)(3.14)(9)
6.28 x 9
