Answer:

\huge\boxed{y=\sqrt{55}}

Step-by-step explanation:

ΔADC and ΔDBC are similar (AAA)

Therefore the cooresponging sides are in proportion:

\dfrac{AC}{CD}=\dfrac{CD}{BC}

Substitute:

AC=6+5=11\\BC=5\\CD=y

\dfrac{11}{y}=\dfrac{y}{5}              <em>cross multiply</em>

(11)(5)=(y)(y)\\\\55=y^2\to y=\sqrt{55}

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.
