The formula for the circumference of a circle is 2*r*pi, where r is radius, and r=d/2.
If d = 6cm, then r = d/2 = 3 cm, and the circumference is 2*r*pi = 6*pi
If d = 12cm, then r = d/2 = 6 cm, and the circumference is 2*r*pi = 12*pi
12*pi/6*pi = 2
The circumference will be B)multiplied by 2.
Answer:
What you put does not make so much sense, so am solving on how I understand what is asking for.
Step-by-step explanation:
10c=13.71 -> I am assuming you want me to solve for c
c/10 = 13.71/10 -> divide 10 on both sides
c = 1.371 or 1371/1000
Answer: C = 1.371 or 1371/1000 or 1 371/1000
4'3 time 4'2 True or False -> I do not understand please explain me what it's asking me in the comment so I can help you
45/100 x 72 = 45/72 x 100 true or false
45/100 x 72 = 162/5 or 32.4
45/72 x 100 = 125/2 or 62.5
Answer: False
16% of 250 = 250% of 16 True or False
16% of 250 is 40 and 250% of 16 is 40.
Answer: True
They will rent 9 cabins And rent 2 tents
Answer:
-1
Step-by-step explanation:
1. subtract 4 from both sides
-x = x+2
2. subtract x from both sides
-2x = 2
3. divide both sides by 2
simplify
x= -1
Hope this helps :)
Answer:
My answer is 8.428571429 ~ 8.43.
Step-by-step explanation:
First you can find log 5 which is 0.698970004 ~0.7. then you can use it to multiply the numbers in the bracket which will be 0.7x(x-7)=1...which will be 0.7x-4.9=1...then you will collect like terms which will be 0.7x=1+4.9 then it will be 5.9÷0.7 which will be equal to my answer above..Thank you for the question
