Answer:
A) The equation for circumference is C=2piR. So Filling in for circle A we have 28.26=2*pi*4.5 so we want to isolate pi which I'm gonna call x for it's easier for me xD. So we're gonna start by dividing 4.5 from each side which is gonna leave us with 6.28=2*x which gives you x(pi)= 3.14. For circle B we have 15.70=2*x*2.5 isolate x by first dividing 2.5 which leaves us again with 6.28=2x and x= 3.14.
B) The equation for area is A=piR^2. So again for circle A we have 63.585=x9^2. This one is harder but also are you sure that the area is 63.585 it's supposed to be 254.469 (We'll come back to this)
C) The observation you can make about the value of pi for circles A and B is that it stays consistent at 3.14
hoped i helped : )
Tautology is when something is repeated in a sentence but using different words. It can be used to enrich the sentence but also it can be needless repetition.
5 statements that would produce a tautology:
1. Lets order a toast sandwich.
2. In my opinion, I think he is right.
3. The Gobi is a very dry desert.
4. The hurricane hit in 3 p.m. in the afternoon.
5. Don't worry, everything is well and good.
The given angles are complementary, therefore:
(5r + 5) + (8r -6) = 90°
13r - 1 = 90
13r - 1 + 1 = 90 + 1
13r = 91
13r/13 = 91/13
r = 7
W?
you mean x or z or O ???

Answer:
76(10) + (-114)10 = (-38)10
Step-by-step explanation:
To express -114 in two complement
First convert to binary = 0000 0000 0000 0000 0000 0000 0111 0010
Change 1 to 0 and o to 1 = 1111 1111 1111 1111 1111 1111 1000 1101
add 1 to = 1111 1111 1111 1111 1111 1111 1000 1110
(76)10 complement = 0000 0000 0000 0000 0000 0000 0100 1100
Adding the two = 1111 1111 1111 1111 1111 1111 1101 1010 (-38)
0(10) in 16 -bit binary =
0000 0000 0000 0000
