Answer:
1 unit
Step-by-step explanation:
The circumference of a circle can be found by multiplying the diameter by pi (around 3.14)
If you rearrange this equation to find the diameter, you get:
If you add your numbers into this, you get:
As pi is around 3.14, you essentially end up with d = 3.14/3.14, and because any number divided by itself is equal to 1, we end up with the diameter being 1.

Firts, Let 
be the repeated decimal that we are trying to convert , so 
equation (1)
Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:
(2)
Subtract equation (1) from equation (2):
Solve for
We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>
