Answer:
22222222/100000000
Step-by-step explanation:
To write 0.22222222 as a fraction you have to write 0.22222222 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number. 0.22222222 = 0.22222222/1 = 2.2222222/10 = 22.222222/100 = 222.22222/1000 = 2222.2222/10000 = 22222.222/100000 = 222222.22/1000000 = 2222222.2/10000000 = 22222222/100000000.
Answer: surface area = 313.2 cm²
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
Answer:
32
Step-by-step explanation:
YZ = ⅗XY.
XY = 20
20 / 5 x 3 = 12
YZ = 12
XZ = YZ + XY
XZ = 20 + 12
XZ = 32
