Consider the following for the next two (02) items that follow: A pot is made from a hollow sphere of inner radius 20 cm by cutting its upper portion horizontally. The height of the pot is 30 cm.
What is the angle made by the line joining the centre of the sphere and any point on the rim of the circular opening with a vertical line passing through the centre?
π/6
The angle made by the line joining the centre and the point on the rim with the vertical line is π/6. Hence, the correct answer is (c) π/6.
