Question

Find the lateral area of the solid figure.

Answer 1

8√3

12√3

24√3
those are the choices, i really appreciate it !

Answer 2

Can you find the area of a 4*4*4 equilateral triangle?

Answer 3

to be honest i have absolutely no idea how to do any of this unit, im willing to try and to learn though, i really need a good grade on this unit

Answer 4

Can you use the Pythagorean Theorem to find the height of the triangle?

Answer 5

4.47?

Answer 6

2squared plus 4squared = 20,
square root of 20 is 4.47 correct?

Answer 7

\(4^{2} = 2^{2} + Height^{2}\)

\(Height = \sqrt{16 - 4} = \sqrt{12} = 2\sqrt{3}\)

Okay, what is the area of the triangle?

Answer 8

i feel really dumb lol what is the formula to find the area?

Answer 9

thanks for your help, as you can see im awful at math

Answer 10

Unacceptable response.

Find the area of the triangle. \(Area = ½\cdot Base\cdot Heaight\) Go!

Answer 11

okay so .5X 2 =1 then 1X 2sqroot3 = 3.464?

Answer 12

We're talking about the whole triangle The base is 4. Try again.

Answer 13

6.93?

Answer 14

Practice using exact values.

\(½(4)(2\sqrt{3}) = 4\sqrt{3}\) That's about 6.93, but the exact value is often more useful.

Okay, back to the original drawing. How many such triangles are there in the figure?

Answer 15

4 including the outside

Answer 16

The important part is 4 if you include the bottom. If you exclude the bottom, you get the lateral surface area.

Okay, can we now answer the question?

Answer 17

i got logged out for inactivity, it wont let me attempt the quiz again until tomorrow, i have other assignments to do though, thanks a lot for your help!
