Area = pi * r^2, right:

616 = 3.1416 * r^2, r^2 = 616/3.1416 = 196.07, r = sqrt(196.07) = 14.002 meters.

Looks like it was written to be almost 14. The answer is 14.002 m, maybe rounded to just 14 m

area = pi r^2  

616 = pi r^2

r^2 = 616/ pi =  196.08 meters

r =  sqrt 196.08  =  14  meters to nearest meter
