Step-by-step explanation:

It is given that Repeated decimals can be written as an infinite geometric series to help convert them to a fraction.  

Consider the repeating decimal below.

We need to find the value of .

is the first term of the series. So,

is the common ratio of the series. So,

Therefore, and .

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
