Question 150283: the radius of a certain brand of lollipop is 12mm
the formula for the volume of a sphere is V=(4/3)(pie)(r)^3. what is the volume of the lollipop? if you are licking at a rate of 1 lick every 5 seconds, and each lick you take removes 40mm^3 from the volume of the lollipop. how many seconds does it take until the lollipop is consumed? how many licks? if you're dealing with a lollipop with bubble gum in the center, how many licks will it take to get to the center, if the gum has a radius of 5 mm. write an equation that tells you the volume of the lollipop in terms of L, the number of licks. write an equation that tells you the radius of the lollipop in terms of L.

1) For the Volume of lollipop ----> direct substitution, with given radius=12mmm;
V=%284%2F3%29%28pi%29r%5E3 = %284%2F3%29%28pi%2912%5E3
V=7238.823mm%5E3
2) Since 1lick%2F5+seconds for every 40mm%5E3
By Ratio & Proportion,
7238.823%2F40=1Lick%2F5seconds
181=1Lick%2F5seconds
There you go, you need to take 181 licks to finish the whole lollipop.
If you cross multiply, you get the time to finish it,
181%2A5=905+seconds=15.08minutes
3) If there's a gum in the center w/ radius 5mm:
To get to the center, we subtract this radius from the radius of the lollipop and mark as R%5B1%5D to be used.
=12-5=7mm=R%5B1%5D --> used to get the new volume
For the Volume= %284%2F3%29%28pi%29%287%5E3%29=1436.755mm%5E3
Again by Ratio & Prop.
1436.755%2F40=1Lick%2F5+seconds=35.92%3E=36Licks before you get to the center where the gum is.
Again, you cross multiply for the time frame,
36%2A5=180seconds=3minutes
Thank you,

the radius of a certain brand of lollipop is 12mm
the formula for the volume of a sphere is V=(4/3)(pie)(r)^3. what is the volume of the lollipop?
:
V = %284%2F3%29pi%2A12%5E3
V = %284%2F3%29pi%2A1728
V = 7238.23 cu mm
;
:
if you are licking at a rate of 1 lick every 5 seconds, and each lick you take removes 40mm^3 from the volume of the lollipop. how many seconds does it take until the lollipop is consumed?
t = 7238.23%2F40 * 5
t = 904.78 seconds
:
how many licks?
L = 7238.23%2F40
L = 181 licks
:
if you're dealing with a lollipop with bubble gum in the center, how many licks will it take to get to the center, if the gum has a radius of 5 mm.
:
Find the volume of the gum center
V = %284%2F3%29pi%2A5%5E3
V = %284%2F3%29pi%2A125
V = 523.6 cu mm is the gum
:
L = %287238.23-523.6%29%2F40
L = 6715%2F40
L = 168 licks
;
write an equation that tells you the volume of the lollipop in terms of L, the number of licks.
:
Using the volume containing the gum
:
V = 6715 - 40L
:
write an equation that tells you the radius of the lollipop in terms of L.
:
Using the one containing the gum;
r = 12 - L%2812%2F168%29
