If there is 20 apples to 10 pears. you could say this as a ratio of 20:10 and then simplify this to 2:1.
<span>This means for every 2 apples there is 1 pear.</span>
Answer:
h = 2 (v − s²) / s
Step-by-step explanation:
v = s² + ½sh
Subtract s² from both sides.
v − s² = ½sh
Multiply both sides by 2.
2 (v − s²) = sh
Divide both sides by s.
2 (v − s²) / s = h
Answer:
Step-by-step explanation:
The given figure is an hexagonal pyramid. It has a hexagonal base and six triangular lateral faces. The formula for determining the surface area of the pyramid is expressed as
Surface area = 3ab + 3bs
Where
a represents the apotherm which is the distance from each side of the hexagon to the center.
b represents the base length
s represents the slant height of the hexagonal base.
From the information given,
a = 5.2 cm
b = 6 cm
s = 12.2 cm
Surface area = (3 × 5.2 × 6) + (3 × 6 × 12.2) = 93.6 + 219.6 = 313.2 cm²
