a solid sphere is cut into 3 equal wedges. the volume of each wedge is V=4/9π^3. solve the formula for r

algol13

$\\ \qquad\quad\sf{:}\dashrightarrow V=\dfrac{4}{9}πr^3$

It is one third of the solid. sphere

$\\ \qquad\quad\sf{:}\dashrightarrow V_{(Sphere)}$

$\\ \qquad\quad\sf{:}\dashrightarrow 3\left(\dfrac{4}{9}πr^3\right)$

$\\ \qquad\quad\sf{:}\dashrightarrow \dfrac{4}{3}\pi r^3$

Now

$\\ \qquad\quad\sf{:}\dashrightarrow \pi r^3=\dfrac{3V}{4}$

$\\ \qquad\quad\sf{:}\dashrightarrow r^3=\dfrac{3V}{4\pi}$

$\\ \qquad\quad\sf{:}\dashrightarrow r=\sqrt[3]{\dfrac{3V}{4\pi}}$

What is the value of x please help me

Tju [1.3M]

Answer:

Step-by-step explanation:

ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:

$\dfrac{LM}{PM}=\dfrac{NM}{QM}$

We have:

LM = 3 + 9 = 12

PM = 9

NM = x + 12

QM = 12

Substitute:

$\dfrac{12}{9}=\dfrac{x+12}{12}$ <em>cross multiply</em>

$9(x+12)=(12)(12)$

$9(x+12)=144$ <em>divide both sides by 9</em>

$\dfrac{9(x+12)}{9}=\dfrac{144}{9}$

$x+12=16$ <em>subtract 12 from both sides</em>

$x=4$
