Question

A circular pin has a diameter of 6.2 centimeters. Which is closest to the area of the pin? Use 3.14 for

Answer 1

`30.18 {cm}^(2)`

Step-by-step explanation

The area of a circular pin is given by

`Area=\pi {r}^(2)`

The diameter of the pin is 6.2cm.

Divide 6.2cm by 2 to get the radius.

`r = (6.2)/(2) = 3.1cm`

The area is

`Area=(3.14)({3.1})^(2)`

`Area=30.1754 {cm}^(2)`

The area of the circular pin is 30.18 centimeters square to the nearest hundredth.
