## anonymous one year ago A SECTOR OF A CIRCLE HAS AN AREA OF 29 SQAURE FEET. FIND THE CENTRAL ANGLE IN DEGREES THAT FORS THE SECTOR IF THE RADIUS IS 7.3 FEET

1. Vocaloid

(x/360)*(area of circle) = (area of sector)

2. Vocaloid

solve for x

3. anonymous

I did , but I got a decimal and I need the answer in radians

4. Vocaloid

huh? the question asks for degrees

5. anonymous

yeah but I got a decimal

6. anonymous

im sorry, can you show me how to work it out

7. Vocaloid

decimals are fine, you can just round

8. anonymous

I know but I need teh naswers in radians

9. anonymous

10. Vocaloid

why??? the question doesn't want radians, it wants degrees

11. anonymous

ok then, how do i get the answers in degrees

12. anonymous

i still have a decimal

13. anonymous

how to i get it into degrees?

14. anonymous

I ned it in degrees

Are of a sector of a circle with central angle $$\theta$$: $$\Large A_{sector} = \dfrac{\theta}{360^o}\pi r^2$$ $$\Large A_{sector} = \dfrac{\theta}{2\pi ~rad}\pi r^2$$

mathstudent55, will that get my answer in degrees

17. mathstudent55

18. mathstudent55

The top formula of the two is in degrees. The bottom on is in radians.

19. anonymous

ok got it

20. mathstudent55

|dw:1437106793705:dw|

21. mathstudent55

|dw:1437106845026:dw|

22. mathstudent55

Remember the 7.3 is squared, so do this in your calculator: 360 times 29 divided by pi divided by 7.3 divided by 7.3

23. anonymous

I will not get an exact number, so do I just round

24. mathstudent55

yes, round it. what do you get?

25. anonymous

62.4

26. mathstudent55

That's what I got, too.

27. anonymous

ok got it

28. anonymous

can you help me with one more thing

29. mathstudent55

yes. pls start a new post. this one is getting too long

30. anonymous

ok

31. anonymous

hey
