Answer:
362880 ways
Step-by-step explanation:
The word dragonfly has 9 different letters.
So, to find how many ways this word can be arranged, we just need to calculate the factorial of 9:
First letter has 9 possibilities
Second letter has 8 possibilities (one used)
Third letter has 7 possibilities (two used), and so on.
So the number of ways is:
9*8*7*6*5*4*3*2*1 = 362880 ways
None of these are equivalent to 34; they're all different values.
Answer:

Step-by-step explanation:
Volume of cone = 
Since we are given that a circular cone has a base of radius r and a height of h that is the same length as the radius
=
=
Surface area of cone including 1 base = 
Since r = h
So, area = 
=
= 
Ratio of volume of cone to its surface area including base :



Rationalizing


Hence the ratio the ratio of the volume of the candle to its surface area(including the base) is 
6a-2(a-1)
6a-2a-2
4a-2
I think it is 4a-2
