Step-by-step explanation:
Area = πr²
2) 11² x 3.14 = 379.94
3) 3² x 3.14 = 28.26
4) 5² x 3.14 = 78.5
5) 6.5² x 3.14 = 132.665
6) 7.2² x 3.14= 162.7776
It looks like 2.25 is the decimal. Since there are four sections between each number, those sections would be divided into quarters. The first quarter is 2 1/4, which is the same as 2.25.
Hope this helps! :)

___
If you number the points 1–6, the points of the 20 triangles will be ...
123 124 125 126 134
135 136 145 146 156
234 235 236 245 246
