Answer:
The volume of a cylinder:
Step-by-step explanation:
To find the volume of a cylinder, you need the this formula:
-Use the given height and radius for the formula:
-Then, solve the formula:
So, the volume of a cylinder is approximately
.
Answer: Linear pairs of angles add up to 180 degrees. A+B=180
Step-by-step explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees
A function is positive if it lies above the x axis.
This function is positive before x = -4, i.e. over the interval
It is negative elsewhere, i.e. over the interval
So, the only correct option is the second one.
