Find the volume of the composite solid. Round your answer to the nearest tenth

Mathematics

Llana [10]3 years ago

Answer:

1131.0 m^3

Step-by-step explanation:

Let h1 represent the height of the top cone, and h2 the height of the bottom cone. The volume of a cone is given by the formula ...

V = (1/3)πr^2·h

so the volumes of both cones together will be ...

V = (1/3)πr^2·h1 + (1/3)πr^2·h2 = (1/3)πr^2·(h1 +h2)

= (1/3)π(6 m)^2(12 m + 18 m) = 360π m^3

≈ 1131.0 m^3

Find the size of the angle <br> 3<br> x<br> .
AlexFokin [52]

Answer:

Given - Two angles measures 2x and 3x

To find - size of 3x

Solution -

2x + 3x = 360° ( Make reflex angle )

5x = 360°

x = 360/5

x = 72°

3x = 3 * 72 = 216°

We need to optimize f(x, y, z) = x + 2y subject to the constraints g(x, y, z) = x + y + z = 8 and h(x, y, z) = y2 + z2 = 4. To f
Evgesh-ka [11]

The Lagrangian is

L(x,y,z,\lambda,\mu)=x+2y+\lambda(x+y+z-8)+\mu(y^2+z^2-4)

with critical points where the partial derivatives vanish:

L_x=1+\lambda=0\implies\lambda=-1

L_y=2+\lambda+2\mu y=0\implies\mu=-\dfrac1{2y}

L_z=\lambda+2\mu z=0\implies\mu=\dfrac1{2z}

L_\lambda=x+y+z-8=0

L_\mu=y^2+z^2-4=0

The second and third equations tell us z=-y, so that in the last equation we find

y^2+(-y)^2=2y^2=4\implies y=\pm\sqrt2\implies z=\mp\sqrt2

and from the fourth equation we get

x+y+z=x=8

So we have two critical points, (8,\sqrt2,-\sqrt2) and (8,-\sqrt2,\sqrt2), which give respective extreme values of f(8,\sqrt2,-\sqrt2)=8+2\sqrt2 (maximum) and f(8,-\sqrt2,\sqrt2)=8-2\sqrt2 (minimum).
