r1 = (12(43r23))/(36r12)
r2 = (36r12)/(12(43r23))
If the radius of the pool is 15 feet, then the radius of the tank is 10 feet.
The tank is completely filled with water and then drains completely into the pool. The volume of the cylindrical tank is V1=36r12, where r1 is the radius of the tank in feet.
The volume of the neighborhood pool is V2=12(43r23), where r2 is the radius of the pool.
Since V1= V2, write an equation that shows r1 as a function of r2.
[Hint: set them equal and solve for r1.]
Write an equation that shows r2 as a function of r1.
[Hint: set them equal and solve for r2.]
