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

Answer:

50 meters

Step-by-step 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!
