how many licks does it take to get to the center of a lollipop that has the volume of 113.0973355292326 cm^3?

let
l = number of licks
v = volume of the sphere
s = surface area of the sphere
k = some constant of dissolution
r = radius of sphere
dv/dl = k*s (the rate of licking is proportional to the current surface area)
dv/dl = k*(4*pi*r^2) (formula for SA of sphere)
dv/dl = kr^2 (allow constant to "absorb" other constants)
For volume of sphere:
v = (4/3)*pi*r^3
r = cuberoot((3/4)(1/pi)v)
dv/dl = k(cuberoot(3/4)(1/pi)v)^2
dv/dl = kv^(2/3) (simplify and absorb constants)
separate variables
v^(-2/3)dv = k*dl
integrate
3v^(1/3) = kl+C
l = (3v^(1/3)-C)/k
Let us use the fact that 0 volume implies 0 licks to get C
0 = (3*0^(1/3)-C)/k
0 = -C/k
C = 0
so we have
l = (3v^(1/3))/k
l = k*v^(1/3) (absorb constants)
so the number of licks is proportional to the cuberoot of the volume
I did the math, you can do the science. You can take a smaller lollipop for instance, find it's volume, see how many licks it takes. That gives you values for l and v that you could plug into the equation to find the value of k. Then to answer your specific question, substitute 113.0973355292326 for the volume and whatever value of k you found for k into the formula and that should spit out the number of licks.
I'm a bit shaky on my results since the conclusion doesn't seem intuitively correct, but I'll run this by a few professors to verify / disprove my calculations.

How does your parents react when you get low marks in test?

It's not even Halloween yet and I'm already seeing Christmas stuff for sale. What's your favourite time of the year?

I do really enjoy Christmas, but sometimes that depends on how and who I celebrate it. It is definitely one of those holidays where how much you enjoy it depends on how much you "put into it"

What's the first thing you notice in a person of the opposite gender?

I am bi, so there are some similarities regardless of gender. However, the way I experience attraction between different genders is a little different. If you're familiar with the split attraction model, you can think of it has sliding around some of the sliders around the various types of attraction for each gender.

A portal to another world opens in front of you. You don’t know how long it will stay open or if you’ll be able to get back after you go through. What do you do?And which world would you choose ? A reminder , you might not be able to get back again !

A portal to the Pokemon world would be interesting.
Another idea would be a portal to an alternate reality that's identical the current one except that everything just "works out" for me. However, in such a case, I would want to have the memory of switching realities to be wiped from me so that I could appreciate the good things instead of expecting them.
