Answer:
A.irrational
Step-by-step explanation:
because 9 can be square to 3 but 11 cant be squared at all.
Area = PI x r^2
Circumference = 2 x r x PI
Using area find the radius )r)
616 = 22/7 x r^2
Divide both sides by 22/7:
196 = r^2
Take the square root of both sides:
r = 14 cm
Now find the circumference:
2 x 14 x 22/7 = 88 cm
Answer : A) 88 cm
