## helpmeplz311 3 years ago This is the worksheet: https://docs.google.com/open?id=0BwF7ycixAkNZRFVEbG4xc1A5ajg And PICTURES 1 and 4 here https://docs.google.com/open?id=0BwF7ycixAkNZX0lvQlIyWWdxamM Are the rectangular and triangular prisms. I have to go now, but if you will drop off your helpful replies, I will give you a medal the minute I log back in in the morning. Please,guys, I really need help.

Do you know how to find the area of a right triangle?

6. helpmeplz311

um,no,let me see

7. helpmeplz311

1/2 times area of rectangle it says

8. helpmeplz311

1/2lw

9. brinethery

Yep. Now do you know how to find the area of a circle? Area of a rectangle?

10. helpmeplz311

area of a circle ispi r 2

11. helpmeplz311

rectangle, bh

12. brinethery

Okay since you know these formulas, these questions you're doing are pretty easy.

13. brinethery

Take 3. on your white sheet.

14. brinethery

You have a triangle on top and a triangle on bottom, both with the same area and same angles.

15. helpmeplz311

brine, i am talking about the nets activity

16. brinethery

Okay well for that triangle, you have to split it up in to 2 right triangles. The left right triangle has a height of 0.5 and a hypotenuse of 1. To find the length of that right triangle, just use the pythagorean theorem where c= the hypotenuse.

Next activity?

18. helpmeplz311

See the worksheet and the photos (blue and yellow) on the other link? thats what i need. the taks worksheet i did with the help of ari

4 for you on the 3rd page. You have 8 right triangles with a height of 6 and a width of 5/2 = 2.5. Since you have 8 of them, you can take the area of one of those right triangles and then multiply that by 8. (1/2)(6)(2.5)(8) = 60 in^2 Now we need to find the area of the square in the middle. (5)(5) = 25 in^2 Take those two values we found and add them together. 60 in^2 + 25 in^2 = 85 in^2

28. brinethery

For some reason the beginning of that message got cut off but you get the idea.

29. brinethery

I don't understand your question for the yellow and blue sheet.
