Answer:
11 feet
Step-by-step explanation:
Use the circumference formula, C = 
d
Plug in 11 as C, and solve for d:
C = d
11 = d
11 = d
So, the diameter is 11 feet
Total Unit of Triangle = 2+4+9 = 15
Value of one unit = 180/15 = 12
So, Angles = 2(12) : 4(12) : 9(12) = 24 : 48 : 108
In short, Your Angles would be: 24, 48 & 108
Hope this helps!
