URGENT WILL MARK BRAINLIEST <br>Show your work and solve for x and y.<br>3x + y = 8<br>2x + 4y = 12

mars1129 [50]

3x+y=8--(1)

2x+4y=12

x+2y=6--(2)

(1)×1 and (2)×3

$\\ \rm\Rrightarrow 3x+y=8$

$\\ \rm\Rrightarrow 3x+6y=18$

Subtract both

$\\ \rm\Rrightarrow -5y=-10$

$\\ \rm\Rrightarrow y=\dfrac{-10}{-5}$

$\\ \rm\Rrightarrow y=2$

Put the value in eq(2)

$\\ \rm\Rrightarrow x+2(2)=6$

$\\ \rm\Rrightarrow x+4=6$

$\\ \rm\Rrightarrow x=6-4=2$

The surface area of a sphere is 576pi square units. Which choice represents the volume of the sphere?

Leona [35]

Answer:

$\large\boxed{V=2304\pi}$

Step-by-step explanation:

The formula of a surface area of a sphere:

$S.A.=4\pi R^2$

R - radius

We have

$S.A.=576\pi$

Substitute and solve for R:

$4\pi R^2=576\pi$ <em>divide both sides by π</em>

$4R^2=576$ <em>divide both sides by 4</em>

$R^2=144\to R=\sqrt{144}\\\\R=12$

The formula of a volume of a sphere:

$V+\dfrac{4}{3}\pi R^3$

Substitute:

$V=\dfrac{4}{3}\pi(12^3)=\dfrac{4}{3}\pi(1728)=(4)\pi(576)=2304\pi$

LuckyWell [14K]

Answer:

A=63.6 approximately

Step-by-step explanation:

P=14.28

p=1/4(2pi*r)

p=1/2pi*r

14.28=1/2pi*r

28.56=3.14*r

r=9...... approximately

A=1/4pi*r^2

A=0.25*3.14*81

A=63.6......approximately
