The formula in getting the area of the circle is:
[tex]A=\pi r^2[/tex]
where r = the radius of the circle and the value of π = 3.14
In the diagram, the radius of the circle is 4 mm. Let's replace the "r" in the formula with 4 mm and "π" with 3.14
[tex]A=(3.14)(4mm)^2[/tex]
Then, simplify.
[tex]\begin{gathered} A=(3.14)(16mm^2) \\ A=50.24\text{ }mm^2 \end{gathered}[/tex]
Therefore, the area of the circle is 50.24 mm². (Option D)
