Answer:

15.9 mm²

Step-by-step explanation:

We solve using Area of the circle formula

Area of a circle = πr²

Diameter of his friend's wand = 4.5mm

Radius = 4.5mm/2

= 2.25 mm

How much wire did his friend need to make the circular part of his wand? Use 3.14 for π

= 3.14 × (2.25mm)²

= 15.89625 mm²

Approximately = 15.9 mm²
