Step 1
Write an expression for the area of a circle
[tex]The\text{ ar}eaofacircle(A)=\pi r^2[/tex]
Where π = 3.14
r = radius = 4ft
Step 2
Substitute in the values and find the area of the circle.
[tex]\begin{gathered} A\text{ = }3.14\text{ }\times4^2 \\ A=50.24ft^2 \end{gathered}[/tex]
Hence the area of the circle = 50.24ft²
