Answer:
π = C / d
Step-by-step explanation:
The circumference of a circle is given by the general formula;
C = 2 * π * r .... or C = π d (r = radius, d = diameter)
We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:
π = C / d
To obtain π, you need to divide the circumference by the diameter.
We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d... it's also convenient to use the diameter.
Answer:
3/4
Because 6 are not white so 6/8 and divide each by 2
6 divided by 2 = 3
8 divided by 2 = 4
= 3/4

Answer:
103 and 68
Step-by-step explanation:
since the difference has to be 35 subtract 35 from 171 (equals 136) then divide it by 2, you get 68 which is your first number, then add 35 back and get 103 for the second number, I hope this helped
Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
(1) 
First, let's expand the expression:
Next, let's factor the quadratic:
Finally, set the equation equal to 
to find the solutions
(2) During the step 
, when you take the square root of both sides, you have two equations, rather than one:
and 
, so the solutions should be 
(3)
Add 
to both sides
Multiply both sides by 
Take the square root of both sides
±
Subtract 
from both sides
