The circumference formula is given by

$C=\pi\cdot d$

where C denotes the circumference, d the diameter and Pi the number 3.1416. In our case, we know that

$C=314\text{ m}$

so, we have the following equation,

$314=\pi\cdot d$

or equivalently,

$\pi\cdot d=314$

and we need to isolate the diameter d. Then, by dividing both sides by Pi, we get

$d=(314)/(\pi)$

or equivalently,

which gives

$d=99.949\text{ meters}$

Thererefore, by rouding to the nearest hundreadth, the answer is: 99.95 meters.
