(The answer MUST BE ONE OF THE ANSWERS BELOW)

Answer 1

c. 50.24 square millimeters

Explanation:

Radius of circle = 4 milimeters.

Area of a circle = πr²

Area = 3.14 × 4² (π = 3.14)

= 50.24 square millimeters

Answer 2

50.24 mm^2

Explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

A = 3.14 ( 4)^2

= 50.24 mm^2
