Question

A Church spire in a form of a regular hexagonal pyramid whose base edge is 8ft and whose altitude is 75ft is to be painted at a cost of 22 dollars per sq. yard. What is the total cost?

Answer 1

Is there any more information to go with the question?

Answer 2

the altitude is 75ft

Answer 3

Do you know the formula for a regular hexagonal pyramid

Answer 4

Basically, find the area then multiply it by 22

Answer 5

I kinda forgot

Answer 6

surface area = 3ab + 3bs

Answer 7

1/2 bh?

Answer 8

That's for a triangle. I posted the formula bove

Answer 9

Never seen that formula before

Answer 10

Show me how it is done pls.

Answer 11

I don't have time to finish this. @wio help him

Answer 12

Answer 13

Well from my brief research it seems like the surface area of a hexagonal pyramid is given by\[\frac{3\sqrt3}{2}a^2+3a\sqrt{h^2+\frac{3a^2}{4}}\] where \(a\) is the length of the base edge and \(h\) is the height.

Answer 14

Does that formula look familiar at all?

Answer 15

Very
