To find the area of a circle, you can use the formula Area = [tex] \pi [/tex] × [tex]r^{2} [/tex]. R represents the radius length.
As the radius length is 4 and the problem has told you to use 3.14 for pi, you can substitute in these values in the formula.
Area = 3.14 × [tex] 4^{2} [/tex]
Area = 50.24
The correct answer is c, 50.2 m²
