Answer:189.97
Step-by-step explanation:
To find the circumference of a circle you use the formula
2πr² we will use 3.14 for π
Your diameter is 11 the radius is half the diamenter so you would divide 11 by 2
Plug 5.5 in with your formula
2π(5.5²) 5.5 squared is 30.25
30.25*3.14=94.985
94.985*2=189.97
