Best ResponseYou've already chosen the best response.0apothem is a line segment from the center of the polygon perpendicular to one of its sides.... AB is ... A is the tip of the pyramid... to the base.. an edge of a side

Best ResponseYou've already chosen the best response.0sqrt 30.25 + 16 sqrt 46.25 p = 6.8 1/2(40)(6.8) + 8^2 = 200

Best ResponseYou've already chosen the best response.1sqrt((4^2) + (5.5^2)) = 6.80073525 doesnt = 10 sqrt((8^2) + (5.5^2)) = 9.7.... is close to 10 If the edge AB that runs slong the side is 10, that means the base is 16

Best ResponseYou've already chosen the best response.18 * 5 * 5.5 = 220 for sides areas .... but to include the base we'd have to do some more calculations

Best ResponseYou've already chosen the best response.1ive been trying to define apothem, slant heaight, and all that stuff; but nothing is consistant. apothem of a pyramid most likely means the height of a face; slant height also means distance up the face; so I cant seem to determine what any of it really means..
