Height and distanceA sphere of radius r is lying on a ground. The sphere makes an angle of measure 60° at point A on the ground,then the distance of the centre of the sphere from A is ______ ? |

Quote:
center of the sphere makes an angle of measure $60^\circ$ with point A relative to the ground?you have a sketch to clarify your problem statement? |

On that basis, the answer would be r/sin(60°), which is 2r/√3, but a different interpretation would make the answer r/sin(60°/2), which is 2r. |

either way, it's just a 30-60-90 triangle problem ... unless the ground isn't level :unsure: |
