Question

Find the area of the circle. Round to the nearest tenth. Use 3.14 for .

26 m
The area of the circle is about
m².

Answer 1

The area of the circle is 2122.6 mm²

Explanation:

To solve this problem we need to use the area formula of a circle:

`a = \text{area}`

`r = \text{radius} = 26 \ \text{mm}`

`\pi = 3.14`

`a = \pi * \text{r}^2`

we replace with the known values

`a = 3.14 * (26 \ \text{mm})^2`

`a = 3.14 *676 \ \text{mm}^2`

`a = 2122.64 \ \text{mm}^2`

Round to the nearest tenth

`a = 2122.64 \ \text{mm}^2 = 2122.6 \ \text{mm}^2`

The area of the circle is 2122.6 mm²
