Answer:
36
3
5
12
Step-by-step explanation:
The circumfrence of a circle is as follows
2πr
For this question π=3.14
So we have
113.04=2πr
solve for r
r= 18
which means that diameter is 36
Just do the same thing with the other questions
18.84=2πr
r=3
31.4=2πr
r=5
37.68=2πr
r=6 which means that the diamater is 12
