The area of a circle is:

$A=\pi\cdot r^2$

As you have the diameter, use it to find the radius: the radius of a circle is equal to the half of the diameter:

$\begin{gathered} r=(d)/(2) \\ \\ r=\frac{17.91\operatorname{mm}}{2}=8.955\operatorname{mm} \end{gathered}$ Then, the area is: 251.80 millimeters
$\begin{gathered} A=(3.14)(8.955mm)^2 \\ A=251.80\operatorname{mm} \end{gathered}$

a dime has a diameter of 17.91 millimeters. What is the area of the face of the dime-example-1
