a pie is cut into 8 equel slices. if a person wants 0.75(pie sign) centimetre of crust, about how many pieces should they take?
I suspect this depends on the radius of the pie.
so then how can i do it? because this it the only detail im given!
There are too many variables (mostly missing). A definitive answer is impossible here. Also, learn to spell five letter words when issuing questions to people potentially preparing for standardized tests. "Equel" means nothing, and your question is utter BS.
