Answer 2

Radius of circle is 1 mm.

Explanation:

Area of circle is 3.14 mm ²

Radius of circle

Area of circle = π × ( radius ) ²

substitute the values

3.14 mm² = 3.14 × ( radius )²

divide the values

3.14mm²/ 3.14 = ( radius) ²

1 mm²= ( radius)²

find the square root of 1 mm²

√1mm² = radius

1 mm = radius

Therefore the radius of circle is 1 mm.
