Answer:

392.5 inches^3

Step-by-step explanation:

So we know the volume of a cylinder is (pie)(r^2)(h)

1. First, find the radius which is 5 inches in this case because the diameter is 10 inches.

2. Second, you have to square the radius which would give us 25 inches^2.

3. Third, you multiply the previous answer (25 inches^2) times the height (5 inches) which would give us 125 inches^3.

4. Lastly, you multiply that answer (125 inches^3) by pie (3.141529..etc) which would give us 392.5 inches^3 ( I used 3.14 as pie) because a cylinder is a 3 dimensional figure.

You welcome :)

Is the line through points P(0, 1) and Q(5, 0) parallel to the line through points R(–4, 3) and S(–5, 4)? Explain.

Answer:

No

Step-by-step explanation:

Let's find the slope of both lines and then compare these slopes:

From (-4,3) to (-5,4) entails a decrease of -1 in x and an increase of 1 in y.  Thus, the slope is m = rise / run = 1/(-1) = -1.

From (0,1) to (5,0) entails an increase of 5 in x and a decrease of 1 in y.  The slope here is m = rise / run = -1/5.

For these lines to be parallel, their slopes must be the same.  That is not the case here, so NO, the lines are not parallel.
