Answer 1

number 7-9
I don't understand how to find the lateral of a cone.

Answer 2

You aren't able to view it? @Directrix

Answer 3

LateralArea=(pi)(r)(g)

Answer 4

the surface area is the area of every face

Question 4 base = 4 x 4 = 16
triangle = 1/2 x 4 x10 = 20

4 triangles Surface Area = 16 + 4 x 20
96 m^2

Answer 5

7. Lateral Area of Cone = pi * r * L where L is the slant height
LA = pi * 5*10
LA = 50 pi = 157.08 square meters

Answer 6

8. LA = pi*r*L where L is slant height
LA = pi * 6 * 10
LA = 60 pi = 188.50 square feet

Answer 7

Question time.

Answer 8

Explain number 4! :D

Answer 9

This is the figure for #8.

Answer 10

@sakigirl --> I thought you wanted to do 7-9.

Answer 11

I understand them

Answer 12

???

number 7-9
I don't understand how to find the lateral of a cone.

Answer 13

I understand it now. Isn't number 9: 304.52?

Answer 14

I haven't done number 9. I'm looking at #4 now. Do you know the formula for the lateral area of regular square base pyramid? Actually, we can just find the area of one triangular face and multiply by 4.

Answer 15

Can we do both? Number 9 first, because it's just checking, and then number 4

Answer 16

Okay, you do number 4 while I do number 9.

Answer 17

alright

Answer 18

I have 4

Answer 19

9. LA = pi*r*L where L is the slant height
LA = pi*6*sqrt(261)
LA = 304.52 square centimeters

Answer 20

What did you get for #4?

Answer 21

189

Answer 22

@Directrix

Answer 23

I have 140.
LA = 4 * (1/2) * 7 * 10

Answer 24

If a pyramid is regular the 4 lateral faces are congruent and have the same area.

Answer 25

My teacher taught us the formula
B+(1/2)Pl

Answer 26

Oh it's asking to find the surface area, not the lateral :P

Answer 27

If you take the 4 triangles 1/2 *7*10 + 1/2*7*10 +1/2 *7*10 + 1/2*7*10 =
[(1/2)*10](7 + 7 + 7 + 7) --> factoring out the [ (1/2)*10], you get (1/2) L times perimeter of the base.

Total Area = Lateral Area and area of Base = 140 + 49 = 189 square meters

Answer 28

This one also

Answer 29

What did you get for slant height?

Answer 30

See, I don't know. I can't find it

Answer 31

Solve for L.

Answer 32

Let me know what you get.

Answer 33

611.7556

Answer 34

@Directrix

Answer 35

yes, that's what I got.
and, then 924981.12 for the lateral area. Yes?

Answer 36

yes

Answer 37

And, total area is ?

Answer 38

572315.22

Answer 39

That is just the base area, I think.

Answer 40

I don't know then. I keep getting that answer

Answer 41

Well, maybe not.

Lateral area = 924981.12
Base area = 571536
Total area = 1 496517.1

Answer 42

Didn't you say that the lateral was 611.76?

Answer 43

924981.12 for the lateral area. Yes?
From above. You agreed to it.

Answer 44

lateral was 611.76? That was for once face of something, I have forgotten what.

Answer 45

When you say "lateral," I do not know if you are talking about lateral area of the solid or area of one lateral face. Try to be more specific.

Answer 46

My figures may be wrong but check yours against them.

Answer 47

I'm so sorry, can you explain everything?
@Directrix
Tired and confused

Answer 48

Can we take the problem to a new thread. I'm getting one "running scripts, about to stop" error message after another.
