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
Rounded to 1 decimal place

hope it helps
16 bc one side is 5ft so the other must be 3 to have an area of 15. Then 5+5+3+3= 16ft
If the area of one is 20, that the area of 30 is 20*30=600 square inches.
