Answer:

64\pi mm² or approximately 201.06 mm²

Step-by-step explanation:

If the diameter is 16 mm, the radius will be 8 mm.

Use the circle area formula, A = \pir², where r is the radius. Plug in 8 as r:

A = \pir²

A = \pi(8²)

A = 64\pi

So, the area of the circle is 64\pi mm² or approximately 201.06 mm²
