Answer:
When y=276, x= 23
Step-by-step explanation:
Since they're directly proportional, when divided they have to equal the same.
180/15= 12 and 276/23= 12
The volume of the solid is 626.12m³
<h3>Volume of composite solids.</h3>
The volume of the given composite solid = volume of cylinder - volume of cube
The volume of cylinder Vc = πr²h
Vc = 3.14(8/2)²(13)
Vc = 3.14(16)(13)
Vc = 653.12 m³
Similarly the volume of the cube:
Volume of cube = 3³
Volume of cube = 27 m³
Volume of the solid = 626.12m³
Hence the volume of the solid is 626.12m³

Answer:
18.72 cubic feet
Step-by-step explanation:
Volume of the aquarium = lwh
- l = 5.2 ft,
- w = 1.8 ft
- h = 2 ft
V = 5.2*1.8*2 = 18.72 cubic feet
D is the correct answer to the equation.
