Question Number 6076 by Rasheed Soomro last updated on 12/Jun/16

Question about Geogebra  •I have drawn a circle in  Geogebra. Now I want to  fill it with colour (because  I need a circular region).  Is there a way?  •Is there a way to fill with  colour any closed figure  composed of line-segment/s  and arc/s?

Yes. Long press any point on the circle   and some options will appear. There  is a colour and transperancy setting  on the options you see. Adjust the   continuous gauge that is under the   colour options to change the strength  of colour which fills the circle.

ThanX a lot!  But this doesn′t work. I have a geogebra  android version. Long press doesn′t  work. Options apear on long press  on the equation of circle which apears  in Algebraic view. Bu there changes  colour of circle itself rather than filling  inside it.  I  have found the option now!

Lot of options are there! But if I  want to fill colour in custom region  (i-e not built-in object)for example intersection area of two  circlcles without colouring remaining  parts of circles?
