Answer: 32/9 or 3.555
Step-by-step explanation:
8/(11/2-13/4)=32/9
So,
To divide a fraction by a fraction, all you need to do is invert the second fraction and multiply the resulting fractions.
Step 1: Flip the second fraction.

Step 2: Multiply the fractions.
First we can conclude that the number is:
8,9 x x, x x x ( 7-digit number ) and the value of ten thousand digit it 1 or 2. But if value of thousand digits must be the double of the value of ten thousand digits, then the number is:
8,924, x x x ( because it can not be 8,912, x x x - that number should be 8,910,000 rounded to a ten thousand digit ).
Then tens and hundreds are same and the least value. That value is zero.
8,924,00 x.
Finally, we add up all values and subtract it from 24.
24 - ( 8 + 9 + 2 + 4 + 0 + 0 ) = 24 - 23 = 1
Answer:
This number is 8,924,001.
Since we know that:
C = 2πr
(With C = 36π ; Substitute in to the equation)
36π = 2πr (dividing both sides by 2π)
r = 18 cm
