MA - Calculus on Instagram: "Deriving the volume of a hemisphere using spherical coordinates takes advantage of the symmetrical nature of the sphere to simplify the calculation. Spherical coordinates are particularly useful when working with spheres and hemispheres because they divide space not only in the radial direction, but also along angles that circumscribe the entire space. In spherical coordinates, you describe a point in space by its distance from the origin, called the radius, plus two
