No, because, none of the combinations of lines can evenly slit spaces. Fold the circle first, and then you can cut the circle into 5 pieces with 2 straight lines.
Cut it diagonally left and right and cut it from top to bottom
Draw 6 circles 'cut' into 3 pieces and shade all of them. Draw one more circle 'cut' into 3 pieces. Shade only one diece in the last circle,
Each piece will be 360/12 = 30 degrees
Cut a round cake in eight equal sized wedge shaped pieces with four vertical cuts, then make one horizontal cut through the center of the cake to equal sixteen pieces.It's slightly more tricky if you are only allowed to cut the horizontal cross-section of the cake (treat the cake as a circle). In this case, first divide the cake with one cut (2 pieces), then cut it again so that it intersects the first cut (4 pieces), then cut it a third time so that it intersects both cuts previously made, at different points (7 pieces), then let the fourth cut intersect all three cuts so far at different points (11 pieces), and let the fifth and final cut intersect all four cuts at different points (16 pieces total).

Divide the circle's circumference into six 60 degree angles and join the angles to its centre then cut it into 6 equal pieces.
Cut it diagonally left and right and cut it from top to bottom
You could use a knife, scissors, or a chainsaw, depending what material your circle is made from.

Cut a pizza into 2 using one straight cut. Stack the pieces and make a straight cut: you now have 22 = 4 pieces from 2 cuts. Stack these and make a straight cut: you now have 23 = 8 pieces from 3 cuts. Continue. After 7 cuts you can have 27 = 128 pieces. You can reduce the number of pieces to 29 if, after the fourth cut, you stack and cut only 11 pieces and thereafter cut just one each time. There are other options which give the same result.
If a circle fraction can, a pie can yes
To cut across the diameter is to bi-sect a circle directly in half...thru the middle...two equal "pie" pieces
