ANSWER
[tex]30.18 {cm}^{2} [/tex]
EXPLANATION
The area of a circular pin is given by
[tex]Area=\pi {r}^{2} [/tex]
The diameter of the pin is 6.2cm.
Divide 6.2cm by 2 to get the radius.
[tex]r = \frac{6.2}{2} = 3.1cm[/tex]
The area is
[tex]Area=(3.14)({3.1})^{2} [/tex]
[tex]Area=30.1754 {cm}^{2} [/tex]
The area of the circular pin is 30.18 centimeters square to the nearest hundredth.
