## anonymous 5 years ago need help on worksheet

1. anonymous

2. anonymous

need help with finding the area ready got perimeter for the first four

3. anonymous

you need only frist 4 question?

4. anonymous

maybe need help in all of them but for now need help on those one first

5. anonymous

6. anonymous

yea

7. anonymous

number 1 you want Perimetr an Area?

8. anonymous

1) P = (3.8m*4) = 15.2m $A = 3.8m^{2}=14.44m ^{2}$

9. anonymous

2) P = 4.7+2.5+2.5+3.2= 12.9ft A = frist extention picture like Rectangle and do area Rectangle A= (4.7ft)*(2.5ft)=11.75ft than find area triangle A triangle = (b*h)/2 base= 4.7ft - 2.5ft = 2.2ft A triangle= (2.2*2.5)/2=2.75ft A rec - A tri = 11.75ft - 2.75ft =9ft

10. anonymous

number 3 , 9 is dimeter or radius?

11. anonymous

if dimeter is 9 than $3) Per, cir = Dime* \pi$ = 3.14* 9 P = 28.26 $A = \pi * r^{2} = \pi3.14^{2} = 63.61$

12. anonymous

4) p = pi*dimeter P = pi * 30ft = 94.25 ft half cir than division by 2 94.25/2= 47.12ft A = pi * r^2 A = pi * 15^2 = 706.86ft^2 half circle than division by 2

13. anonymous

A=353.43ft^2

14. anonymous

later use caculator check some time acident I hit wrong number

15. anonymous

so what the area and perimeter for number 4

16. anonymous

I did post A= 353.43ft^2 the rest let me write on the paper and I will post

17. anonymous

you need 11 n 10?

18. anonymous

no

19. anonymous

let me work anothe number

20. anonymous

ok

21. anonymous

22. anonymous

for number 7 and 8 it say find the height

23. anonymous

7 said find the circumference 8 find the height , yes I find the heigh

24. anonymous

9 find the base

25. anonymous

look the question again

26. anonymous

?

27. anonymous

i need go rest room i be back

28. anonymous

i think it 7.5 not 15 for number 9

29. anonymous

number 9 Area is 97.5 and heigh is 13 find tha base (97.5*2)/13= 15

30. anonymous

check :( 13*15)/2= 97.5 ?

31. anonymous

ok it right

32. anonymous

can you check my answer for number 5 and 6 i got for number 5 40 and for number 6 i got 21

33. anonymous

5 and 6 take very long not easy ,pentagon has 5 side ie mean 5 triangle ,I have to find each side and 5 time triangle and use Trigonomertry to find base and heigh, do you have another question post you can come back , I will attach file When I'm done, 5 and 6 exactly the same only one 5 side one 6 side

34. anonymous

35. anonymous

I will do alll give me more time, if you have some thing to do come back ,I'm working now

36. anonymous

37. anonymous

6) A=(3.5*3.03)/2= 10.6/2=5.3 cm^2 6 side have6 triangls than (6*5.3) = 31.8 cm^2 Area hexagon is 31.8cm^2 good cluck with your home work

38. anonymous

thank you so much

39. anonymous

u r wel come , r u understand now?

40. anonymous

yea go to go thank for everything i would of ben lost without you helping me

45. anonymous

I better not give email, but I will help if I see your name post a question

46. anonymous

ok thank.

47. anonymous

bye

48. anonymous

number 7 C =29.85m not 29.85Pi ,I was wrong

49. anonymous

I triple check the rest is correct,
