I need help, I answered every question but my teacher is asking for the work for each question, my dad helped me with this assignment and he is out of town so i have no idea how to do the work. Could someone help explain how i got the answer to each problem, my dad is out of town so he can't help me and Im clueless. I need it done soon, any help would be very appreciated <3 thank you


What is the circumference of the circle if the radius is:

1. 6
37.7
 
2. 2
12.57

3. 5x
 
4. 3x-4
 
5. 5x/3
 
What is the radius if the circumference is:

6.  30x(pi)
15x
 
 
7. 4x-10pi
(2x/pi) - 5
 
8. (5/2)pi
(5/4)
 
9. 14pi
7
 
10. (x + y)pi
(x+y)/2
 
What is the length of the arc if:

11.  r=10 n=20
10(pi)/ 9
 
12. r=3 n=6
pi/10
 
13. r=4 n=7
7(pi)/45
 
14. r=2 n=x
x(pi)/90
 
15. r=y n=x
x*y*pi/180
 
What is the radius if:

16. n=30 L=1/3xy(pi)
2xy 

 
17. n=40 L=8/9(t)(pi)
4t
 
18. n=15 L=(21/36)pi
7
 
19. n=5 L=1/2pi

Re: geometry homework

Circumference = 2*pi*radius
Go back here when you have tried at least number 1 and 2.
