Can you cut a circle into 5 pieces with 2 straight lines?
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.
How many cuts does it take to divide a log into 6 equal sized pieces?
5 (unless you cut lengthwise).
How do you cut a cake into 16 pieces using 5 cuts?
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).
What is the measure of the central angle of each sector if you divide a circle into five equal sectors?
360 degrees / 5 pieces = 72 degrees
If it takes 20 minutes to saw a log into 5 equal pieces how long will it take to saw a second log that is the same size as the first into 10 equal pieces at the same rate?
Assuming the pieces are not rearranged so that more than one piece is cut at a time, then: 5 pieces requires cuts, so each cut takes 20 minutes/4 each. 10 pieces require 9 cuts, therefore they will take 20/4 × 9 minutes = 45 minutes.
