For this case we must follow the following rules of rounding
1) If the previous number is greater than or equal to five, then the next number increases by one unit
2) If the previous number is less than five, then the next number stays the same
Therefore, the steps for rounding to the nearest tenth is:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
Rounding to the nearest tenth is:
5.6
Answer:
1) We observe that 3 is less than 5.
2) Therefore, the next number stays the same
5.6

Answers: B, C, F</h3>
Each of these are closed figures formed by straight line segments. Think of fencing in an area (not necessarily a rectangle) using various straight fence sections. The length of each section does not have to be the same.
Side notes:
- Choice A is not a polygon because the figure is not closed.
- Choice D is not a polygon because it is not composed of line segments only. Choice D is an ellipse instead.
- Choice E is not a polygon due to the curved portion.
Given:
Circle C and circle R are similar.
The length of arc AB is 
The radius of circle C (AC) = 4 unit
The radius of circle R (QR) =6 unit
To find the length of arc QP.
Formula
The relation between s, r and 
is
where,
s be the length of the arc
r be the radius
be the angle.
Now,
For circle C
Taking r = 4
According to the problem,
or, 
[ eliminating from both side]
or, 
or, 
Again,
For circle R
Taking, r = 6 and we get,
The length of arc QP is
or, 
Hence,
The length of QP is 
. Option C.
