The formula to find the circumference of a circle is :

To find the radius we would divide 3.3 by 2
The radius is always HALF of the diameter.
3.3/2=1.65
Now we know r=1.65
So we plug that into the circumference formula:

pi=3.14
Once you multiply all the numbers together you get:
C=10.36m
That is an ratio, what are you asking for??
Answer:
3.7 hours
Step-by-step explanation:
Pat could do the job alone in 8 hours.
Patti could do the job alone in 7 hours
Output = Rate * time
Let the rate at which pat does the work = Rp
Let the rate at which Patti does the work = Rt
Let X be the total output
Rp * 8 = X
Rp = X/8
Rt * 7 = X
Rt = X/7
If both pat and Patti pick apples, we have
(Rp+Rt)T = X
(X/8 + X/7)T = X
[(7X + 8X)/56]T = X
[X(7+8)/56]T = X
Divide both sides by X
[(7+8)/56]T = 1
(15/56)T = 1
T = 56/15
T = 3.7 hours
Answer:
7(x-4)
Step-by-step explanation:
You can use an Algebra calculator btw.
Step-by-step explanation:
Substitute y = -2 in:
4x - (2 × -2) =8
4x - (-4) = 8
4x + 4 = 8
4x = 4
x = 1
Check:
4x - 2y = 8
4 -2y = 8
-2y = 4
y = -2
