Area = 3.14 x r^2
Circumference = 3.14 x D
Where r = radius and D = diameter
We also know that D = 2r
And since for circle Area = 114
114 = 3.14 x r^2
And since D = 2r , r = D/2
So, (D/2)^2 x 3.14 = 114
(D^2) / (2)^2 = 114 / 3.14
D^2 = (114 x 2^2) / 3.14 = (114 x 4) / 3.14
D^2 = 456/3.14
D = (456/3.14)^(1/2) = (145.22)^(1/2)
D = 12.05
And so now since C = circumference = 3.14 x D
C = 3.14 x 12.05 = 37.837
And this answer rounded to the nearest tenth is 37.8m
