An above-ground swimming pool in the shape of a cylinder has a diameter of 18 feet and a height of 4.5 feet.If the pool is fille

iragen [17]

Answer:

The volume of the water in the pool is 1,017 cubic feet

Step-by-step explanation:

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$r=18/2=9\ ft$ ----> the radius is half the diameter

Remember that

$1\ ft=12\ in$

$6\ in=6/12=0.5\ ft$

To find out the height of the water, subtract 0.5 feet from the height of the swimming pool

$h=4.5-0.5=4\ ft$

assume

$\pi =3.14$

Find the volume of the water

$V=(3.14)(9^{2})(4)$

$V=1,017\ ft^3$

11111nata11111 [884]

Answer:

89 milliliters liquid was in the container before George added more .

Step-by-step explanation:

Let us assume that the liquid was in the container before George added more be x .

As given

George's container was partially full.

Then he added 177 milliliters more liquid to the container.

Now the container has a total of 266 milliliters of liquid.

Than the equation becomes

liquid was in the container before George added more + liquid added = Total liquid in the container

Putting all the values in the above

x + 177 = 266

x = 266 - 177

x = 89 milliliters

Therefore 89 milliliters liquid was in the container before George added more .
