Connections Pool Service needs to fill up a neighborhood pool in
Lakewood. They use a cylindrical tank on the truck to transport water
from the warehouse to the pool.
The tank is completely filled with water and then drains completely into the pool. The volume of the cylindrical tank is V = 36πr, where r, is the radius of the tank in feet.
The volume of the neighborhood pool is V₂ = 1/2(4/3pi r3 2) where r₂ is the radius of the pool.

a. Since V₁=V₂, write an equation that shows r1 as a function of r2.

[Hint: set them equal and solve for r₁.]
