The formula to calculate the area of a circle is:
[tex]A=\pi r^2[/tex]Where r is the raidus. Remember that the radius is one half of the diameter.
Thereby, the area of the bottom of the pool is:
[tex]\begin{gathered} A=\pi(10)^2 \\ \\ \Rightarrow A=314.16 \end{gathered}[/tex]Thereby, we can conclude that:
