Answer:
16m
8m
50.24m
200.96m^2
Step-by-step explanation:
13. 8*2=16
14. 8m
15. 2pi r = 2* pi* 8= 50.24
16. pi r^2 = pi * 8^2= 200.96m^2
Answer:
TU= 4 mm
Step-by-step explanation:
a^2+b^2=c^2
3^2+b^2=5^2
9+b^2=25
b^2=16
b=4
Answer:
The second one, the second to last one, and the last one.
Step-by-step explanation:
The second one is negative because if you add a negative number with a positive number it becomes negative.
The second to last one is zero because if you add a negative and a positive number that is the same number then it becomes zero.
And the last one, they are both simply positive.

the place i got this from tbh i don't understand what you want for an answer but i tried, so here is a website that i got these from i hope it helps you.
Step-by-step explanation:
Evaluate for a= 1/3
3(1/3)+4(1/3) = 7/3
Evaluate for a= 1.5
(3)(1.5)+(4)(1.5)
=10.5
Evaluate for a=
(3)(2)+(4)(2)
=14
I'm assuming those are two fractions being divided. I just write it out. It looks scary but it's really not. Just do this:
~=this is my dividing sign when not in fraction form cause I don't have an actual sign here.
9/14 ~ 5/12
Then you KCF(Keep, Change, Flip). Keep the first number the same. Change the dividing sign to multiplication. Then flip the last fraction so that it is now 12/5.
The problem now stands as:
9/14 • 12/5
Simplify and the you have your final answer. I recommend looking up the keep change flip video by flocabulary in case you haven't checked it out yet. It really helped me learn this method. Hope this helped!!
