Someone please help me with this.

Radius=r=0.7m
Volume=231m^3
Height=h

$\boxed{\sf Volume=\pi r^2h}$

$\\ \sf\longmapsto π(0.7)^2h=231$

$\\ \sf\longmapsto 0.49πh=231$

$\\ \sf\longmapsto πh=\dfrac{231}{0.49}$

$\\ \sf\longmapsto 3.14h=471.4$

$\\ \sf\longmapsto h=\dfrac{471.4}{3.14}$

$\\ \sf\longmapsto h=150m$

2x-y=-10 y=4 what is the solution

ratelena [41]

Answer:

(- 3, 4)

Step-by-step explanation:

given the 2 equations

2x - y = - 10 → (1)

y = 4 → (2)

Substitute y = 4 into (1) and solve for x

2x - 4 = - 10 ( add 4 to both sides )

2x = - 6 ( divide both sides by 2 )

x = - 3

solution is (- 3, 4 )
