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
Answer:
The screenshot below should explain the answer
Answer: .8
Step-by-step explanation: 4/5 = .8
U have a dashed line...meaning there is no equal sign in the problem
u have a y int (where ur line crosses the y axis) of 5
u have a slope of :
(0,5),(3,1)......(1- 5) / (3 - 0) = -4/3
it is shaded below the line, so it is less then
ur inequality is : y < -4/3x + 5 <===
