$5027.2\ ft^2$

Step-by-step explanation:

Given

The radius of the circle is $r=40\ ft$

The area of the circle is given by $\pi r^2$

Insert the value of radius and get the area to play

$\Rightarrow \text{Area A=}\pi \times 40^2\\\\\Rightarrow A=3.142\times 1600\Rightarrow A=5027.2\ ft^2$

Thus, the area to play is $5027.2\ ft^2$
