Given that the radius is 38 cm, then we have the following using the formula for the area of the circle:
[tex]\begin{gathered} A=\pi\cdot r^2 \\ r=38 \\ \Rightarrow A=(3.1416)\cdot(38)^2=4536.47 \\ A=4536.47\operatorname{cm} \end{gathered}[/tex]therefore, the area of the circle with radius r=38cm is 4536.47cm^2
