Answer: Approximately 530.66 square millimeters

===============================================

Work Shown:

A = pi*r^2

A = 3.14*13^2

A = 3.14*169

A = 530.66 square millimeters

We can abbreviate "square millimeters" into "square mm" or into "mm^2".

This value is approximate because pi = 3.14 is approximate.
