The formula for circumference is 2

r, where r is equal to radius.
It states to use 3.142 for pi
It also provides you with the diameter, not the radius, so you have to divide it by two to get 4.5
2*3.142*4.5= approximately 28.278 or 28.3
In case you want the working out -
You will want to put all these fractions over the same denominator, the lowest common multiple is 180
-2/9
180/9 = 20
20 x -2 = -40/180
A -7/12
180/12 = 15
15 x -7 = -105/180
B -1/15
180/15 = 12
12 x -1 = -12/180
C -1/3
180/3 = 60
60 x -1 = -60/180
D -1/9
180/9 = 20
20 x -1 = -20/180
-105 < -60 < -40 < -20 < -12
A < C < x < D < B
B and D
Answer:
18x
Step-by-step explanation:
18x times 18x
so the side is 18x because it was squared
They are not. The easiest way to tell this is by multiplying the last number of each parenthesis together. This should always result in the last number in the equation. However, -8*5 does not equal -30, so these are not the true factors.
