Tiles

Answer 1

36

3

5

12

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
