The radius of the Brazilian coin is 13.5 mm

How to determine the radius?

The circumference is given as:

C = 84.78 mm

The circumference of a circle is:

C = 2πr

So, we have:

2 * 3.14* r = 84.78

Evaluate the product

6.28 * r = 84.78

Divide both sides by 6.28

r = 13.5

Hence, the radius of the Brazilian coin is 13.5 mm
