How to calculate the distance from the moon using an object like a penny (As well as knowing the diameter of the moon) using trig.
what? you need measurements..is this a question off a text book ?
no its not. Using a penny you can calculate the distance from the moon to yourself.
oh idk how to do that :/ sorry!!
keep the penny at some distance ( few cm) such that it blocks the view of the moon, then u can measure the angle subtended by the diameters of the two. well u get sumthing like this |dw:1359388725848:dw| angle=arc/radius arc = diameter of the moon radius ur ans :)
