Using Cavalieri's Principle, what is the general formula for the volume of a cone?

Anit [1.1K]

Answer:

The volume for a cone and pyramid are the same, V = 1/3 Bh where B is the area of the base.

Step-by-step explanation:

So even though the base is a different shape, as long as the areas and heights are the same, they will have the same volume.

What is the missing expression that would make the left-hand-side of the equation equal to the right-hand-side?

o-na [289]

Given:

The equation is

$\dfrac{???}{x-2}/\dfrac{x^2-1}{x^2-4x+4}=\dfrac{5(x-2)}{x-1}$

To find:

The missing value.

Solution:

Let the missing value be k.

$\dfrac{k}{x-2}/\dfrac{x^2-1}{x^2-4x+4}=\dfrac{5(x-2)}{x-1}$

$\dfrac{k}{x-2}\times \dfrac{x^2-2(x)(2)+2^2}{x^2-1^2}=\dfrac{5(x-2)}{x-1}$

Using the formulae $(a-b)^2=a^2-2ab+b^2$ and $(a-b)(a+b)=a^2-b^2$ .

$\dfrac{k}{x-2}\times \dfrac{(x-2)^2}{(x-1)(x+1)}=\dfrac{5(x-2)}{x-1}$

$\dfrac{k(x-2)}{(x-1)(x+1)}=\dfrac{5(x-2)}{x-1}$

Cancel out the common factors from both sides.

$\dfrac{k}{x+1}=5$

Multiply both sides by (x+1).

$k=5(x+1)$

Therefore, the missing value is 5(x+1).

The average temperatures for two of the world's hottest places are given. Determine which location has the warmer average temper

zubka84 [21]

Answer: City A, $0.28^{\circ}C$

Step-by-step explanation:

Given

The temperature of city A is $86.7\ ^{\circ}F$

The temperature of city B is $30.1^{\circ}C$

We know, $32^{\circ}F=0^{\circ}C$

So, $86.7^{\circ}F=30.38^{\circ}C$

$30.38>30.1$

Clearly, the average temperature of city A is more than city B

The difference in temperature is $30.38-30.1=0.28^{\circ}C$

Find the measure of the missing angles .

maw [93]

Answer:

d = 90°

e = 41°

f = 139°

Step-by-step explanation:

d + 90° = 180° (Angles in linear pair)

-> d = 180° - 90°

-> d = 90°

e = 41° (vertical angles)

f + 41° = 180° (Angles in linear pair)

-> f = 180° - 41°

-> f = 139°
