Using sympy:

A spherical tank is 3 m tall and therefore has a capacity of about 14000 L (NOTE that 3m is its diameter, and one cubic meter is 1000 L). You have been asked to put level lines on the tank showing the depths where the tank contains 1000, 5000, and 10000 L of liquid.

(a) Use calculus to determine the height of each line (to the nearest cm).

(b) Plot the circular cross-section of the tank and the level lines (NOTE the lines do not have to stay within the circle).
