Answer:
the diameter is 14cm
Step-by-step explanation:
to get the circumference of a circle you would need to times the diameter (d) by pi or in this case n which is 3.1
this result is 43.4cm
now to figure out the diameter we would have to reverse this so the equation would be
d=43.4/n
which is the same as d= 43.4/3.1
the result of this is d= 14
so the diameter is 14cm.
