Circumference=2(pi)r or (pi)d
You know that Circumference=113.04
You know that the diameter=2x+4
Plug what you know into the equation and solve for x.
C =(pi) d
113.04=(pi)(2x+4)
Answer:
ET = 80/A^2
Step-by-step explanation:
First, isolate the variables that you need, which is E and T, using the two equations you were given.
EA = 8
E = 8/A (divide A on both sides to isolate E)
AT = 10
T = 10/A (divide A on both sides to isolate T)
Now, substitute.
ET --> (8/A) x (10/A) = 80/A^2
I made this graph for you- the red is the 80%, and the green is the leftover 20%.
Answer:
28.3 (b)
Step-by-step explanation:
To solve circumference, you will need to use the equation C = 2 *pi* r
for this, we will use 3.14 for pi and the radius is 4.5 so this is how we need to solve it
C= 2 pi (4.5) Solve 2*4.5
C= 9 pi Now we input 3.14 for pi and multiply
C= 9(3.14)
C= 28.26 Now we round to the nearest tenth to get
C=28.3
