The answer would be 636.4 cm3 because you first have to find the volume of the sphere including the rubber wall, which is 904.32 cm3. Next, you would find the volume of the sphere inside the rubber, so subtract 2 cm from the radius of 6 cm and put 4 cm into the formula to get 267.9567. Last, subtract the internal volume from the external volume to get 636.3733 cm3 and round it to the tents place.
(4/3) x 3.14 x 6^3 = 904.32
(4/3) x 3.14 x 4^3 = 267.9467
904.32 - 267.9467 = 636.3733
Answer:
<em>1885.5 m^3 of water</em>
<em></em>
Step-by-step explanation:
I'll assume this is the complete question
<em>Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the pool. When the pool is filled to this recommended level, approximately how many cubic feet of water will it contain? Use π = 3.14
</em>
<u><em>The pool forms</em></u><em> a cylinder with a radius of 12 feet and a height of 4.5 feet.</em>
<em></em>
height of pool = 4.5 ft
radius of pool = 12 ft
height of water is 4 inches below pool top
<em>12 inches make 1 ft</em>
4 inches = 4/12 ft = 0.33 ft
Therefore, height of water = 4.5 - 0.33 = 4.17 ft
<em>volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed</em>
volume of cylinder formed by the water = volume of water = πh
volume = 3.14 x x 4.17 = <em>1885.5 m^3 of water</em>
For the first one, we have
Multiply this by and you end up with
For the second one,
I’m pretty sure it’s flooding of roads near the coast but idk for sure
