Answer:
C
A parallelogram has 2 sets of parallel lines, but this has only one.
1/2 + 1/3 = (3*1)+(2*1) / (2*3) = (3+2)/6 = 5/6
tinha 5/6 de litro
para 1 litro faltam 4/6 de litro
para 3 litros faltam 2 litros e 4/6 de litro ou, simplificando:
4/6 = 2/3, logo, faltam 2 litros e 2/3 de litro.
Answer: ![77.283km^{2}](https://tex.z-dn.net/?f=77.283km%5E%7B2%7D)
Step-by-step explanation:
The formula for the lateral area of a cone
is:
![L.A=\pi r h](https://tex.z-dn.net/?f=L.A%3D%5Cpi%20r%20h)
Where:
is the radius of the circular base of the cone
As we know its diameter
, its radius is ![r=\frac{d}{2}=10km](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Bd%7D%7B2%7D%3D10km)
is the height of the cone
![L.A=\pi (10km)(2.46km)](https://tex.z-dn.net/?f=L.A%3D%5Cpi%20%2810km%29%282.46km%29)
This is the lateral area of the volcano with the shape of a cone
The answer to this question is C
2.8 hours because 3.5 divided by 1.25 is 2.8
