the diameter of the circle is
D = 16 cm
so the radius is r = D/2 = 16/2 = 8cm
the area of the circle is,
[tex]A=\pi\times r^2[/tex]put r = 8 and pi = 3.14
[tex]\begin{gathered} A=3.14\times8^2 \\ A=200.96\text{ cm\textasciicircum{}2} \end{gathered}[/tex]thus the area of the circle is 200.96 centimetres squared.
