Answer: 1:(12^2*10.8)/3=518.4 2: v = 392(3.1415)/3 = 410.5 3: (Πr^2*h) Π*9*15=424
Step-by-step explanation:
So.. let's say ∡AGB and ∡BGC are say "a" units wide, and ∡CGD and ∡DGE are "b" units wide
notice the picture below
all angles added up together, will make up just a flat line, or 180°
now, notice in the picture, the ∡BGD is really just " a + b " wide, notice the green angle in the picture of ∡BGD, well, we know what a + b is
Since it is a hexagon and it has 6 sides (and we assume it is regular since it doesn't tell us otherwise) then the hexagon will have 6 lines of symmetry (:
B. 4 right angles
perpendicular lines always create 90° angles
THE CORRECT ANSWER IS:
Mary sells 43 units; Jay sells 51 units; Abby sells 54 units
HOPE THIS HELPFUL. :)
