I am working on some book writing. For that I need to draw circle filled with red color.
I tried \circle but it generate black circle only. How can I fill it with color?

The MnSymbol package provides a \bigcircle command, however, it is a little smaller than you want. You can use \scalebox from the graphicx to make the circle a little bigger. It is still a little high, so \raisebox can be used to adjust this. Putting this together into a macro:
\newcommand\Bigcircle{\raisebox{-0.5mm}{\scalebox{1.7}{$\bigcircle$}}}
produces:
Another, arguably more flexible, approach is to use tikz to draw the circle. Again, you need to adjust the baseline of the circle, but it is much easier to change the size of the circle and the width of line. It is also very easy to draw other shapes, such as squares, this way. The macro
\newcommand\TikCircle[1][2.5]{\tikz[baseline=-#1]{\draw[thick](0,0)circle[radius=#1mm];}}
shows one way of doing it this way to use tikz. (The \TikCircle command takes an optional argument that gives the radius of the circle in milimeters. By default, the radius is 2.5mm so \TikCircle is the same as \TikCircle[2.5].) This produces:
Here is the full code as a minimal working example:
\documentclass{article}
\usepackage{amsmath}
% mnsymbol approach
\usepackage{MnSymbol,graphicx}
\newcommand\Bigcircle{\raisebox{-0.5mm}{\scalebox{1.7}{$\bigcircle$}}}
% tikz approach
\usepackage{tikz}
\newcommand\TikCircle[1][2.5]{\tikz[baseline=-#1]{\draw[thick](0,0)circle[radius=#1mm];}}
\begin{document}
MnSymbol:\bigskip
$\frac34 \Bigcircle\frac14$
\bigskip
Tikz:\bigskip
$\frac34 \TikCircle\frac14$
\end{document}
Finally, you probably want to add some space around these symbols. I would treat these as "mathematics operators" and use \mathop:
\newcommand\TikCircle[1][2.5]{{\mathop{\tikz[baseline=-#1]{\draw[thick](0,0)circle[radius=#1mm];}}}}

One easy way would be to use
TikZas in the following MWEwhich produces
Where the first
reddefines the line style of the drawn circle to be red and thefill=redspecifies, that its solid red. You could also useblack,fill=redto obtain a red circle with a black border. Finally of course the.5exis the radius of the circle.
