Find the volume of the entire figure to the nearest whole number. Use 3.14 for Pi.

Alja [10]

Answer:

1733.28 m³ or approximately 1733 m³

Step-by-step explanation:

Cone - 1/3πr²h

Cylinder - πr²h

Cone - 1/3(3.14)(6)²(10) ⇒ 376.8

Cylinder - (3.14)(6)²(12) ⇒ 1356.48

1356.48 + 376.8 = 1733.28 m³

Approximately 1733 m³

Solve the equation for the height?

Mars2501 [29]

Answer:

$\bold{h=\dfrac{S-2\pi r^2}{2\pi r}=\dfrac{S}{2\pi r}-r}$

Step-by-step explanation:

$\bold{S=2\pi r^2+2\pi rh}\\\\\bold{2\pi r^2+2\pi rh\ =\ S}\\\\{}\qquad -2\pi r^2\quad\ \ -2\pi r^2\\\\{}\quad \bold{2\pi rh\ =\ S-2\pi r^2}\\\\\div(2\pi r)\quad\ \div(2\pi r)\\\\\bold{h=\dfrac{S-2\pi r^2}{2\pi r}=\dfrac{S}{2\pi r}-r}$

Can anyone please help me! if solve it I will give 30 points and brainliest.

The biggest cone that can fit into a cube of side 3cm would have a diameter of 3 and height of 3, therefor if the volume of a cone = πr^2h*1/3, then:
Volume = π*1.5^2*3*1/3
= 2.25π
= 9π/4 cm^3

S= 2LW + 2LH + 2WH<br> solve for W

Darina [25.2K]

Rewrite the equation as

2lw+2lh+2wh=a.2lw+2lh+2wh=a

Subtract

2lh

from both sides of the equation.

2lw+2wh=a−2lh

Factor

2w out of 2lw+2wh.

2w(|+h)=w−2lh

Divide each term by

2(l+h)

and simplify.

.w=a−2lh2(l+h)
