Answer is C = 18.84 mm

Step by step

If the area of the square is 36mm, we know
A = S^2 or side squared because the sides are the same length.
So the side length = 6mm

This means the diameter of the circle is also 6mm.

Circumference of a circle is found using
C = 2 TT r

We know diameter is 6mm, so radius is 3mm (r = 1/2D)

C = (2) (3.14) (3)

C = 18.84 mm

Answer:

18.84 mm

Explanation:

The side of the square is the diameter of the circle so to find the side of the square we just find the square root of 36 which is 6

And now to find the circumference we multiply 6 by 3.14 and that is equal to 18.84mm

Hopes this helps please mark beainliest
