inner is 352m and outer is 396m
first you know that
c=πd
then you solve it inner is diameter
simple the circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!
