Which value is an approximate of √27 (square root of 27) A: 3.0
B: 5.2
C: 9.0
D: 13.5

C) 5.2

Step-by-step explanation:

The real thing looks like this 5.19615242 …

But if you round it, the answer would be 5.2.

b

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
