Answer:
50.2
Step-by-step explanation:
The equation to find the area of a circle is [tex]a=\pi r^{2}[/tex].
First, substitute your numbers in place of the variable:
[tex]A=\pi 4^{2}[/tex]
Next, square the radius:
[tex]A=\pi 16[/tex]
Then, multiply it out to get:
A=50.24
Then, pick the closest answer which is 50.2
