Answer:
The first step is to find the volume of the two hemispheres.
Step-by-step explanation:
Since the 2 hemispheres have the same radius, we can simply find the volume of a sphere.
Volume of sphere
Volume of solid
= volume of cylinder -volume of 2 hemispheres
Let's find the volume of the cylinder.
Volume of cylinder
Thus, volume of solid
This is a problem of Difference-of-squares. We know that for a difference of squares
the factorization is given by:
To learn this you need to remember that a <em>difference</em> means <em>subtraction.</em> So applying those concepts we can solve this problem step by step.
Applying distributive property:
Applying distributive property again:
Simplifying:
<em>The correct answer is C</em>

Answer:
C: -3/7
Step-by-step explanation:
Put an extended line over each direct point you see and then count the graph it takes to reach the nearest point.
Here is a picture to better explain it!
The answer is 12.5.
Explanation:
The first point that touches the graph is at (2, 25). In two hours, the rider travels 25 miles, so then to get to one hour, you divide 25 by 2 and you get 12.5. If you look on the graph, it’s about right where the point lays.
