Not sure if you wanted answers or explanation on what to do. Ill just do the explanation and if you want the answers just lmk C:

R=1/2 d, and C=pi*2r. So you basically take the given number and plug it into these formulas.

Answer:

21. D = 5.67(rounded to the hundredths)

R = 2.84(rounded to the hundredths)

22. D = 13.4

C = 42.08(rounded to the hundredths)

23. C = 33.28(rounded to the hundredths)

R = 5.3

24. D = 1

R = 1.57 or pi/2

Step-by-step explanation:

Formula: C/pi = D

D = 2r

pi = 3.14

21. D = 17.8/3.14 = 5.67(rounded to the hundredths)

R = 5.67/2 = 2.84(rounded to the hundredths)

22. D = 6.7*2 = 13.4

C = 13.4 * 3.14 = 42.08 (rounded to the hundredths)

23. C = 10.6 * 3.14 = 33.28(rounded to the hundredths)

R = 10.6/2 = 5.3

24. D = 3.14/3.14 = 1

R = 3.14/2 = 1.57 or pi/2

What is the reason for each step in the solution of the inequality?<br><br> −2(x+3)−4&gt;4x+30
DochEvi [55]
You would have to first distribute the -2 to the x+3 which gives you -2x-6.  Then you would subtract the 4 which gives you -2x-10 on the left side.  Now you have the equation -2x-10>4x+30.  Move the 4x to the other side giving you         -6x-10>30.  Now add the 10 from the other side which leaves you with -6x>40.  Now remember when you divide by a negative in an inequality, you HAVE TO flip the sign giving you the answer of x<-20/3.

Exterior angle theorem <br> what is the value of u? I’m willing to give brainlist!!
KengaRu [80]
Answer: 45

Explanation: two angles that form a Line always equal 180 degrees, so we start with the equation 180-u+47, which is the measure of the missing interior angle measure. All of the angles inside of a triangle also equal 180 degrees, so we can set up this equation to find U:
u-18+u+(180-u+47)=180
We can start to simplify by first simplifying what’s inside the parenthesis:
u-18+u+153-u=180
Then you solve the equation to get
U=45 degrees
