If your goal is to plot the text along the circle, you can use this code. Adopt the starting angle (135) and the angular offset (5) to your needs.

centerY = 0;
Radius = 10;
viscircles([centerX ,centerY ], Radius ); 
word = 'my circled text';
i = 1; 
for alpha = 135:-5:135-(numel(word)-1)*5
    text(10*cosd(alpha), 10*sind(alpha), word(i), 'Rotation', alpha-90, 'FontSize', 20); 
    i = i+ 1; 
end

centerX = 0;
centerY = 0;
Radius = 10;
viscircles([centerX ,centerY ], Radius );   % it creates a circle with given parameters
text(centerX, Radius,'R = 10') % to add text to your plot

You would have to chage the axes if you want to change position of your text.

xlim([-Radius-3 Radius+3])
ylim([-Radius-3 Radius+3])
text(centerX, Radius+1,'R = 10') % Note it will display text at Y = 11
