Best ResponseYou've already chosen the best response.0for this one i need to find the slant hight, lateral area, and the surface area

Best ResponseYou've already chosen the best response.0okay on the slant height you use this formula =Lateral Area of a regular pyramid: ½ perimeter × slant height = 96 on this one

Best ResponseYou've already chosen the best response.0because see tha base of it is got dotted line which means you take half of 16 = 8 and * that by 12 which gives us 96

Best ResponseYou've already chosen the best response.0on frist one to get surface area use this formula Surface Area = Lateral Area + n × Bases.

Best ResponseYou've already chosen the best response.0i should of put this at the top... they are multiple choice.. for the cone the choices are a) 20 b) 10.6 C08.9 d) 14.4 e)7.1

Best ResponseYou've already chosen the best response.0(25/4+144/4)^(1/2) = (169/4)^(1/2) = 13/2 (169/4+25/4)^(1/2) = 6.96 for side of pyramid

Best ResponseYou've already chosen the best response.06.96 for side of pyramid so would this be the slant height?

anonymous

Best ResponseYou've already chosen the best response.0?, the side going from one of the bottom corners to the top.

Best ResponseYou've already chosen the best response.0It's the longest side on the pyramid

Best ResponseYou've already chosen the best response.0for the pyramid: the slant height choices are: a)4.5cm b)5.5cm c)6.5cm d)6cm e)7.8 for the lateral area choices are: a)57.5cm^2 b)65cm^2 c)32.5cm^2 d)78cm^2 e)90cm^2 for the surface area: a)57.5cm^2 b)65cm^2 c)32.5cm^2 d)78cm^2 e)90cm^2

Best ResponseYou've already chosen the best response.0Ok, slant height is the height from the midpoint on the base to the top. So 6.5

Best ResponseYou've already chosen the best response.0for SA, .5bh*4 + b^2 b=5, h=6.5 (5)(6.5)(2)+5(5) 90cm squared

Best ResponseYou've already chosen the best response.0I'm guessing lateral area means without the base, so it's probably 65

Best ResponseYou've already chosen the best response.0All you need to know to do these problems to use the Pythagorean theorem on Right triangles to find the missing side, and area of triangles is simply .5base times height.
