These cones are similar. find the volume of the smaller cone. round to the nearest tenth.

Kamila [148]

Answer:

Volume of the smaller cone = 8.34 cm³

Step-by-step explanation:

"If two figures are similar, their dimensions will be proportional.

Following this rule,

Ratio of the dimensions of two cones = $\frac{\text{Radius of the large cone}}{\text{Radius of the small cone}}$

= $\frac{r_2}{r_1}$

= $\frac{5}{2}$

= 2.5

Similarly, "ratio of the volumes of two similar figures is cube of the dimensional ratio".

Ratio of the volumes = (ratio of the dimensions)³

$\frac{V_1}{V_2}=(2.5)^3$

$\frac{131}{V_2}=15.625$

$V_2=\frac{131}{15.625}$

= 8.384 cm³

≈ 8.4 cm³

Therefore, volume of the smaller cone is 8.4 cm³.

In □PQRS side PQ∥ side RS. If m∠P = 108degree

natka813 [3]

<h2>Given :-</h2>

In □PQRS side PQ∥ side RS. If m∠P = 108degree

and m∠R = 53degree

m∠Q and m∠S.

<h2>Solution :-</h2>

According to angle sum property

P∠Q=180−∠P

∠Q=180−108

$\boxed{\sf{\angle Q = 72°}}$

For angle S

∠S=180−∠R

∠S=180−53

$\boxed{\sf {\angle S = 127°}}$
