## anonymous 5 years ago Can someone tell me if this is right?? finding the slant height.. i got 473.96

1. anonymous

2. amistre64

what does it mean by slant height? the edge or the face?

3. anonymous

idk.. it just says find the slant height of the regular pyramid

4. amistre64

i googled it and it says slant height is the distance up the face. that distance is equal to sqrt(15^2 + 6^2) sqrt(225 + 36) = sqrt(261) right?

5. amistre64

16.155 is what I get.....

6. anonymous

okay.. i got 17.2

7. amistre64

the slant height is just the hypotenuse of he right triangle that is formed by 15 and 12/2

8. anonymous

I agree with Amiestre64

9. amistre64

dont let the hero title fool ya..... im just an idiot in disguise :)

i got 2 hours to write up a paragraph on how well Johnson and Johnson company would be as a stock purchase...... procrastinating :)

Indeed. $15^2 + 6^2 = \text{Slant height}^2$ $\rightarrow \text{Slant height} = \sqrt{15^2 + 6^2} = \sqrt{225+36} = \sqrt{261} \approx 16.1555$

slant height for this one

13. anonymous

Employ the same technique.

14. amistre64

is that a 13 or an 18?

15. anonymous

18

16. anonymous

The 'legs' of the hypotenuse are 5 an 18

17. amistre64

sqrt(5^2 + 13^2) then sqrt(25 + 196)

18. amistre64

er.... 169 :)

20. amistre64

........ugh, maybe I do need to write that paragraph lol

21. amistre64

18^2 not 13^2

22. amistre64

8 and 1 are your legs there

23. anonymous

where did the one come from

24. amistre64

since the height of thing comes down to the middle of a side, the length you use for the bottom leg is just half of a side....2/2 = 1

25. anonymous

oh

26. anonymous

so for this one slant height is 18.68

27. anonymous

this one slant height = 8.06

28. anonymous

I get 8.246 for that last one.

29. anonymous

Oh wait no. You're right.

30. anonymous

8.06

31. anonymous

it would be ft ^2 right

32. anonymous

No. You have $\sqrt{ft^2 + ft^2}$ So it will be in ft.

33. anonymous

ok
