20. The surface areas of two similar solids are 216 m² and 1014 m². The volume of the larger one is 2197 m³. What is the volume
Andrei [34K]

Answer:

  216 m³

Step-by-step explanation:

The ratio of linear dimensions is the square root of the ratio of area dimensions.

  s = √(216/1014) = √(36/169) = 6/13

Then the ratio of volume dimensions is the cube of that. The smaller volume is ...

  v = (6/13)³·2197 m³ = 216/2197·2197 m³ = 216 m³

The volume of the smaller solid is 216 m³.

We have then:

For x = 1:

10-2 (1)\\10-2\\8

For x = 2:

10-2 (2)\\10-4\\6

For x = 3:

10-2 (3)\\10-6\\4

For x = 4:

10-2 (4)\\10-8\\2

For x = 5:

10-2 (5)\\10-10\\0\\

Answer:

The value of the expression in ordered pairs is:
