Answer 2

@triciaal can you help with this?

Answer 3

@Nnesha

Answer 4

don't like these 3D
need to use pythagorean theorem

Answer 5

the base is a hexagon of side 4 agree?

Answer 6

Yes

Answer 7

for each of 6 "triangle face "area = 1/2 * base * perpendicular height

Answer 8

So 12•4•6•1/2?

Answer 9

Theorem 12.4 The surface Area of a Regular Pyramid is S = B + 1/2 Pl. where B is the area of the base, P is the perimeter of the base and l is the slant height.

Answer 10

What does 12.4 mean?

Answer 11

I did puthagorean theorem and i got 12.6

Answer 12

Theorem 12.4 from a text (like the name of process)

Answer 13

Ohok but do you do puthagorean first? I did and got 12.6 what do you do next

Answer 14

@jim_thompson5910 can you please help me clean this up?

Answer 20

well I gave you the formula straight from the text
I am not the expert I tried to help and even tried to get extra help for clarification
sorry if that's not enough

Answer 21

I needed help for lateral area firat but you gave formula for surface area. So i looked up a formula for lateral atea of. Hexagonal pyramid but the formula asks for base edge so how do you find base edge?

Answer 22

Nvm i found the lateral area and surface area thx anyways

Answer 23

I gave the lateral area = I said each face is a triangle and you have 6
The area of each is 1/2 bl where b is the length of the side and l is the slant height

Answer 24

Whats the formula for surface area of hexagonal pyramid

Answer 25

S = B + 1/2 Pl

Answer 26

L is the slant height right and what is p?

Answer 27

perimeter

Answer 28

perimeter of the base = 6 b

Answer 29

Ok hold on

Answer 30

I got 40 when i did 4+1/2(6)(12) is it correct? @triciaal

Answer 31

no B = base area b= length of side

Answer 32

Base area is 144

Answer 33

Ok so the answer would be 144+24squareroot3??
