a)Draw a line thru the center intersecting 2 points on either sides of the circle
b)Using radius of the same circle, draw 2 arcs in both intersecting points. Along with the straight line, this will cut out 4 sectors, with the rest of the circle sum to get for the 5th portion.

You can cut a round cake into eight parts with three cuts, but you can't cut a circle into eight parts with three straight lines.
Draw two diameter lines, then draw a circle inside the circle.
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
