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:
Part 1) 
Part 2) 
Part 3) 
part 4) 
Part 5) 
Step-by-step explanation:
we know that
In a rectangle opposite sides are parallel and congruent
The measure of each interior angle is 90 degrees
The diagonals are congruent and bisect each other
step 1
Find the length of side PR
we know that
----> by opposite sides
we have

therefore

step 2
Find the length of side PQ
we know that
----> by opposite sides
we have

therefore

step 3
Find the length of diagonal PS
we know that
---> the diagonals bisect each other
we have
---> given problem
therefore

step 4
Find the length of diagonal QR
we know that
---> the diagonals are congruent
we have

therefore

step 5
Find the length of RT
we know that
---> the diagonals bisect each other
we have

substitute

Answer:
The answer to your question is:
Fraction he has review = 17/36
Fraction he have to study = 19/36
Step-by-step explanation:
Data
Monday studied = 2/9
Tuesday = 1/4
Fraction he has review = ?
Fraction he has left = ?
Process
As the denominator is 9, consider the whole is 9.
Then: Fraction left on Monday = 9/9 - 2/9
= 7 / 9
Fraction left on Tuesday = 7/9 - 1/4
= (28 - 9) / 36
= 19 / 36
Fraction he has review = 17/36
Fraction he have to study = 19/36
