The Formula for the Volume of Fluid $V$ In a Spherical Tank of Radius

Short Answer

The formula for the volume of fluid $V$ in a spherical tank of radius $r$ when the depth of the fluid $h$ is $V=\frac{\pi h^{2}}{3}(3 r-h)$ A $21.7 \mathrm{~m}$ wide tank is filling with liquid oxygen at a constant rate of $20.5 \mathrm{~L} / \mathrm{s}$ . How fast is the surface of the oxygen rising when the height is $1.06 \mathrm{~m}$ ?
