Determine the surface area of each pizza by using the formula
area=PIE(3.14159)*radius*radius
If the sum of the small and the medium is greater than the area of the large then they are a better deal. If the reverse is greater then the large is a better deal.
small and medium!You have a choice at the local pizza place: for the same price you can get either one large pizza or both a
you are trying to cheat on homework or school work aren't you?
Good kids stay in school and don't cheat on Y! Answers be a good kid!
Weigh them, large one first, then small and medium together.
well a large pizza has 8 good size slices
a medium has 6-8 depending on the cut but with the 8 the slices are much smaller.
a small pizza has 4.
so if u get a small and a medium your getting "10-12" slices but they do not compare to that of a large one. get the big pizza its worth it!
Assuming that the total area of pizza is the only concern...
Area is pi*r^2
If the total areas for either deal were equal, then:
pi*r1^2 = pi*r2^2 + pi*r3^2
Eliminate pi from both sides, and you get a pythagorean statement:
r1^2 = r2^2 + r3^2
If half the diameter of the large pizza squared is larger than than the sum of half the diameter of the small and medium pizzas squared (individually and respectively) then the large pizza is the better deal, otherwise, getting two pizzas is the better deal.
