To find the area of a circle, start with the formula for the area of a circle.
Area = [tex]\pi[/tex][tex]r^{2}[/tex]
Notice that we are given the radius of the circle so we can plug the radius into our formula.
Area = [tex]\pi[/tex] (4 cm)²
Area = 16π cm².
Now, remember that π is approximately equal to 3.14. We can estimate the area of the circle by plugging in 3.14 for π.
(16) (3.14) = 50.24 cm³.
Therefore, the area of the circle is approximately equal to 50.24 cm³.
