Answer:
The two pink or Rose colored ones are parallelograms
Step-by-step explanation:
They both have lines that are one pair of parallel lines to each other
Area for circle is πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6
No it is not possible if the pen has a rectangular or square shape
