the formula for the area of the circle is
[tex]A=\pi r^2[/tex]
it is given that the area of the circle is 201.1
[tex]\begin{gathered} 201.1=\frac{22}{7}\times r^2 \\ r^2=\frac{201.1\times7}{22} \\ \end{gathered}[/tex][tex]\begin{gathered} r^2=\frac{1407.7}{22}=63.98 \\ r=\sqrt[]{63.98}\text{ or }\sqrt[]{64} \\ r=7.98\text{ }\approx8 \end{gathered}[/tex]
we know that the diameter of the circle is twice of the radius
so, diameter D = 2r = 2 x 8 = 16
so the answer is approx 16
