The formula to find circumference of circle is given by

$C = 2\pi r$

Where r is radius of circle and pi =3.14

We are given Circumference here as 361π

Plugging the value in the formula :

$361\pi = 2\pi r$

r=361/2 = 180.5

radius of circle is 180.5.

We know that Diameter is double of radius.

So diameter = 2*180.5 = 361

Answer : diameter of circle is 361.
