Their are 6 equilateral triangles in a regular hexagon:
The area of one triangle = (x²√3)/4, then:
1st answer: The area of the hexagon base: is 6 TIMES the area of one equilateral triangle [or, needed for 2nd, question, TOT AREA:(6x²√3)/4] = (3x²√3)/2] unit²
2nd answer: :
Volume of pyramid: (base area)(height)/3
Volume of pyramid: (3x²√3).(3x)/3 (because height = 3x, given)
Then Volume of pyramid= 3x³√3 unit³.
3 is the answer for the second question
and 6 for the 1st
Answer:
640 dm
Step-by-step explanation:
200+40+400=640dm
Answer:
the first one is
+2 +4 + 8 + 16 +32
he multiply by 2 every time he add numbers so its 65
the second one he make this
-8 -4 -2 -1
every time he Take from numbers he devide by 2
so its 5
the third one
+6 +18 + 54 + 162
every time he add he multiply by 3
ao its 162 +80 =242
the fourth one is
+33 +66 + 132 +264
he multiply by 2 every time he add
so its 267+264=531
the fiveth one is
he put the roots
2²,3²,4²,5²,6²
so the answer is 36
Step-by-step explanation:
A 65
B 5
C 242
D 531
E 36
hopefully its helpful man
