Answer:
A≈452.39
Step-by-step explanation:
Area of circle =
πr²
= π12²
A=45
A=kx/y
where k is constant
substituting the values for k
k= 20×9/6=30
when x=9, y=6
A= 30×9/6=45

Step-by-step explanation:
Answer:
9
Step-by-step explanation:
If we find the factors of each and rewrite them like this:
16, 16 x 9, 16 x 9 x 9, etc.
We notice we are multiplying by a factor of 9 every time we increase the number of subscribers.
Well first you must find what 71/2 is equal to:
71 / 2 = 35.5
Now you should convert this to a decimal instead of a percent. All you have to do is move the decimal two places to the left when going from percent to decimal:
35.5% = .355
Now that you know the decimal value, you want to know what number is 12 35.5% of. To do this, think, if you were wondering what is 10% of 100, you would multiply 100 by .10 so in this case since you are going the opposite way, you would divide 12 by .335, which gives you:
35.8208955224
This can be approximated to:
≈35.82
