Question

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 18 feet and a height of 16 feet. Container B has a diameter of 12 feet and a height of 20 feet. Container A is full of water and the water is pumped into Container B until Container 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?​

Answer 1

answer: 1808.6 cubic feet

to find the volume of the empty space in container A after the water is pumped to container B, subtract the volume of container B from container A.

the formula for finding the volume of a cylinder is this:
V = (π)(r^2)(h)
where V stands for volume, r stands for radius, h for height, and π = 3.14

Container A volume:
V = (π)(9^2)(16)
V = (3.14)(81)(16)
V = (3.14)(1296)
V = 4069.44 cubic feet

Container B volume:
V = (π)(6^2)(20)
V = (3.14)(36)(20)
V = (3.14)(720)
V = 2260.8 cubic feet

Subtract

4069.44 - 2260.8 = 1808.64 cubic feet
1808.64 rounded to nearest tenth is 1808.6 cubic feet
