Water is poured into a cone until the height of the water is one third of the cone's height, $s$s cm.
Which of the following expressions correctly represents the remaining volume in cubic centimeters?
$\frac{1}{3}\pi\left(\frac{1}{3}s\right)^2s-\frac{1}{9}\pi\left(\frac{1}{3}s\right)^2s$13π(13s)2s−19π(13s)2s cm3
$\pi\left(\frac{1}{3}s\right)^2s-\pi\left(\frac{1}{9}s\right)^2\frac{s}{9}$π(13s)2s−π(19s)2s9 cm3
$\frac{1}{3}\pi\left(\frac{1}{3}s\right)^2s-\frac{1}{3}\pi\left(\frac{1}{9}s\right)^2\frac{s}{3}$13π(13s)2s−13π(19s)2s3 cm3
$\pi\left(\frac{1}{3}s\right)^2s-\pi\left(\frac{1}{9}s\right)^2s$π(13s)2s−π(19s)2s cm3
