Question

The circular clock face in the clock tower on campus has a radius of about 4 meters. What is the area of the clock to the nearest square meter? Use 3.14 as an approximation for pi

Answer 1

50 meters

Explanation:

The area of a circle is
`\pi r^2`, so assuming that
`\pi` is 3.14, we can make the equation
`3.14 \cdot r^2`.

Assuming the radius is r, which is 4, we can substitute the values into the equation.

`3.14 \cdot 4^2\\3.14\cdot16\\50.24`

This question is asking for the area to the nearest square meter so rounding 50.24 to the nearest square meter results in 50.

Hope this helped!
