Which measurement is a good estimate for the area of a circle if the radius is 4 meters?

The rule of the area of the circle of radius r is
[tex]A=\pi r^2[/tex]Since the radius of the circle is 4 meters, then
[tex]r=4[/tex]Substitute the value of r in the rule above by 4
Use pi = 3.14
[tex]\begin{gathered} A=3.14(4)^2 \\ A=3.14(16) \\ A=50.24\text{ m}^2 \end{gathered}[/tex]Then the area of the circle is about 50 square meters
The answer is the last choice
