Theo containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 30 feet and a height of 18 feet. Container B
has a diameter of 26 feet and a height of 19 feet. Container A is full of water and the
water is pumped into Container B until Conainter B is completely full.
After the pumping is complete, what is the volume of the empty space inside
Container A to the nearest tenth of a cubic foot?

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

We have given that the shape of a

cylinder Container A has a diameter of 30 feet and a height of 18 feet.

diameter =30 feet and height =18 feet

Therefore

What is the formula for volume of cylinder ?

For cylinder A,

Similarly for cylinder B,

h=19

radius

volume of cylinder B

After pumping all of Cylinder  A into Cylinder B there will remain empty space in B

The percentage this empty space is,

of the entire volume is

which is 26.12 %  when rounded to the nearest tenth.  

Therefore,

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.
