Q$1)$ Problem definition: You are required to design a spherical tank to hold water. The radius

$(10)$

CLO $2$

$R=3\mathrm{.}5m.$ The volume of the liquid it can hold can be calculated as$,$

$V=h^2\frac{(4R-h)}{5}$

Where $V=$ volume $(m^3),h=$ depth of the water tank $(m)$ and $R$ is the radius of tank $(m)$

Apply appropriate numerical technique to calculate to what depth $(h)$ the tank must be

filled so that it can hold $49$ cubic meters?
