Circumference formula: 2πr

2 multiply the π by the radius which will be 4.5 because to get the radius u will have to to do 9 divide 2 which will be 4.5.

Calculate that in the calculator and you’ll get:

C=28.3 ( I rounded to the nearest tenth)

Answer:

i think it would be 28.26

Step-by-step explanation:

because C=2 pie r and D=2 r (solving for C=pie d =pie . 9 = 28.27433 then just round and thats how you get 28.27 (sorry if its confusing) (im not good at explaining but i am smart)
