Drag the tiles to the correct boxes to complete the pairs. Match each radius or diameter of a circle with its approximate circumference.
Tiles

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

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
