Least to Greatest: 0.7m, 0.93 cm, 95 cm, 108 cm, 1.3m
Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft
Square root of 144 is 12
square root of 169 is 13
