What is the Volume of a hexagonal pyramid shown if the hexagon has a side length of 4 inches and the height of the pyramid is 12
inches?
1 answer:
Answer:
Step-by-step explanation:
<u>Volume formula:</u>
- V = 1/3 Bh, B-base area, h- height
<u>Base area:</u>
- B = 3√3a² / 2 = 3√3*4² / 2 = 41.57 in (rounded)
<u>Volume:</u>
- V = 1/3*41.56*12 = 166.24 in³

Answer:
x= -21
Step-by-step explanation:
6/7x=-18
divide both sides by 6/7
------------
x= -21
------------
2x+5y=21, x+y=3
y=3-x
2x+5y=21
2x+5(3-x) =21
2x+15-5x=21
2x-5x+15=21
-3x+15=21
-3x=21-15
-x=6/3
-x=2
x=-2

Answer:
12
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√[4 - (-8)]² + (10 - 10)²
√(12)² + (0)²
√144 + 0
√144
=12
