Step-by-step explanation:

The area of a circle is square of it's radius multiplied by 22/7.

The area of this ring will be difference between the area of a circle with diameter of 38mm (radius 19mm) and area of a circle with diameter of 32mm (radius 16mm).

(19*19*22/7) - (16*16*22*7) = 1134.57 - 804.57 = 330

So the area of one side of this ring will be 330 sq.mm.
