The answer for your question is A
Answer:
16.875
Step-by-step explanation:
Our goal here is to create a copy of line segment PQ, through various steps. Let's start with drawing line segment PQ, respectively point R a fixed distance away from the segment.
It would be wise to use a compass in this case, and a ruler for certain.
So we have this segment PQ, and point R a " fixed distance " away from PQ.
( 1. Extend a compass to match with the length of PQ,
( 2. Move this compass ( without changing it's length ) so that one endpoint matches with point R
( 3. Now draw an arc with this compass, where this line will be
( 4. Take your ruler and draw a straight line from this point R to your arc. It would be wise to draw this line to the middle of the arc you created.

I have done these questions before, so I can assure you that this experiment is proved correctly!
<em>Answer:</em>
for question 4 the asnwer is 1.7
for question 6 the answer is 2
<em>Explanation: </em>
The volume of 4 is 18 length × width × height so 3 × 3 × 2 = 18
The mass 32kg divided by the volume 18 = 1.777777778
-----------------------------------------------------------------------------------------------
The volume of 6 is 90 length × width × height so 10 × 3 × 3 = 90
The mass 180kg divided by the volume 90 = 2
