\theta =90
\end{cases}\implies s=\cfrac{(90)\pi (2)}{180}\implies s=\pi$

I have a very expert technique that is very easy to changed decimal into mixed fraction

All you have to do is nevermind of the integer sign

So we will move on to 30.75

The first is write it in word so 30.75 is thirty and seventy five hundreths

Then analyze so 30 is the whole number and 75 is numerator then 100 is the denominator

So it is 30 75/100 then simplify it to the lowest terms

= 123/4 or 30 3/5
