The Moon has an almost spherical form.

Observes the previous application. Calculate the following:

a) Which are the coordinates of the points A and B? How much distance are they?

b) Calculates:

-- The area of the spindle understood between the meridians that pass for the points A and B.

-- The volume of the spherical wedge understood between the meridians that pass for the points A and B.

c) Calculates:

-- The area of the cap that proves to take the parallel one that passes for A and B.

-- The volume of the spherical segment that is formed to the cut a plane that passes for the parallel one of the points A and B, with the sphere.
