Segment VY is a midsegment of trapezoid FEDC. Find x.
1 answer:
Answer:
x = 12
Step-by-step explanation:
The midsegment VY is half the sum of the parallel bases , that is
VY = , then
3x + 18 = (x + 96) ← multiply both sides by 2 to clear the fraction
6x + 36 = x + 96 ( subtract x from both sides )
5x + 36 = 96 ( subtract 36 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12

Answer:
V ≈ 68.63 cm³
Step-by-step explanation:
the volume (V) of a sphere is calculated as
V = πr³
the volume of a hemisphere is half the volume of a sphere, so
V = ×
πr³ =
πr³ , then
V = π × 3.2³
= π × 32.768
≈ 68.63 cm³ ( to 2 dec. places )
The correct option is: A. 80 cm³
Explanation
Diameter of the coin, cm.
So, the radius, cm.
As the coin is circular, so..
Area of each circular surface, cm²
Now for finding the amount of plastic for making each coin, we will find the Volume of each coin first.
As the thickness () of the coin is 0.5 cm, so Volume of each coin,
As you need to make a batch of 50 coins, so the total volume of 50 coins [Rounded up to the nearest multiple of 10 cm³]
So, the amount of plastic you will need for making a batch of 50 coins is 80 cubic centimeter.
