## Allythegymnast 2 years ago 23. Name three faces of the cube above that intersect at point G. (1 point) a. DHGC, CBFG, GFEH b. ABFE, ADHE, ABCD c. DCBA, GEBF, GFEH d. GDAF, CBFG, GFEH 26. Find the surface area of the cylinder to the nearest tenth of a square unit. Use pi. = 3.14. a. 206 cm2 b. 100.5 cm2 c. 623 cm2 d. 412 cm2 mc0262.jpg nar0021.jpg

I'll give you one face for the cube, and you should be able to find two more. One is ABCD.

4. TammisaurusRex

As for the surface area of the cylinder.. do you know the formula to find the surface area of a cylinder?

5. Allythegymnast

no..

6. ConnexussKidd96

which unit and lesson

7. Allythegymnast

unit 2 lesson 16. 7th grade

8. TammisaurusRex

Here's the formula for the surface area of a cylinder: $2\pi r ^{2} + 2\pi r h$ Where r = radius h = height $\pi = p i$and pi = 3.14

9. TammisaurusRex

Do you know how to plug your values in?

10. ConnexussKidd96

ohh im in 10th grade lol

11. Allythegymnast

No....

12. Allythegymnast

i tried but i got a WAY different answer then the answers provided..

13. TammisaurusRex

What values did you plug into where? (what did you use for the radius and what did you use for the height?)

14. Allythegymnast

wait i think i got it is it 412???

15. TammisaurusRex

Well, here's how it should look before solving:$(2)(3.14)(4^{2}) + (2)(3.14)(4)(12.4)$

16. TammisaurusRex

If you simplify that by squaring the radius, then it's: (2)(3.14)(16) + (2)(3.14)(4)(12.4) How would you go bout solving this?

Yes! Very good!

19. Allythegymnast

Thx!!
