Step-by-step explanation:
Given:
- radius = 7 metres
- height = 2 metres
- π = 3.14
To Find:
- Volume of the cylinder
Solution:
Use the formulae of the volume of cylinder:
where,
- π = 3.14
- r = radius
- h = height
According to the question:
- radius = 7 metres
- height = 2 metres
Substitute the values onto the formulae in order to find out the volume:
<u>Hence,we can conclude that:</u>
The volume of the cylinder is approximately
307.7m³.
Given:
The function is:
To find:
The result of the operation .
Solution:
If , then the graph of f(x) is reflected across the x-axis to get the graph of g(x).
We have,
The given operation is:
So, it will result in a reflection across the x-axis.
Therefore, the correct option is A.
