Answer:

5127079.21 cubic feet

Step-by-step explanation:

The silo is in the shape of a cylinder and a cone.

The volume of the silo will be the sum of the volumes of the cylinder and the cone.

Therefore, its volume is:

V = \pi r^2h + \frac{1}{3} \pi rH

where r = radius of cylinder and cone

h = height of cylinder

H = height of cone

The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:

130 - 25 = 105 feet

Therefore, the volume of the silo is:

V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3

The volume of the silo is 5127079.21 cubic feet.

Find the missing side. Round to<br> the nearest tenth.<br> Х<br> 28°<br> 15<br> x = [?]
Effectus [21]

Given:

The right triangle with base 15 and hypotenuse x.

The measure of angle between base and hypotenuse is 28 degrees.

To find:

The value of x.

Solution:

In a right angle triangle,

\cos \theta=\dfrac{Base}{Hypotenuse}

In the given triangle,

\cos 28^\circ=\dfrac{15}{x}

x=\dfrac{15}{\cos 28^\circ}

x=\dfrac{15}{0.8829476}

x=16.98855

Round the value to the nearest tenth.

x\approx 17.0

Therefore, the value of x is 17.0 units.
