Answer:
The answer is 1/6y+1/6(y+12)-2
Step-by-step explanation:
I used a math calculator.
The volume of the cylinder is equal to the sum of all spheres
the volume of 1 sphere is V1=4/3×pi×(1/2 x)³
simplified V1=1/6×pi×x²
we conclude that the volume of the cylinder is V2=270V1
V2=45×pi×x³
also the V2 can be calculated from the cylinder
V2= base(circle)×height
V2=(3x)²×pi×h=9x²×h
so we have
9x²×pi×h=45×pi×x³
simplified h=5x
First you need to change the equation to 3 < x/2 + 1
then we can treat it like a normal equation.
subtract 1 from each side to get 2 < x/2
then multiply both sides by 2 to get rid of the fraction and we have
4 < x and we switch it around to get
x > 4 as our answer! :)
