A silo is shaped like a cylinder with a cone on top. The radii of the bases of the cylinder and cone are both equal to 8 feet. T

dangina [55]

Answer: 6702.1

Explanation:
Volume of cylinder = πr^2h
= π(8^2)25
= 1600 π

Volume of cone = πr^2(h/3)
= π(8^2)(25/3)
= π (64)(25/3)
= (1600 π)/3

Add these two numbers
= 1600 π + (1600 π)/3
= (4800 π+ 1600 π)/3
= 6400 π/ 3
=6702.06≈6702.1

Corrected Question

Given a triangle with two sides 4.1 cm and 6.7cm and an Included angle of $35^\circ$ . Use the Law of Cosines to determine the length of the third side of the triangle.

Answer:

(D) 4.1cm

Step-by-step explanation:

Given a triangle with two sides 4.1 cm and 6.7 cm and an included angle of $35^\circ$ .

Using Law of Cosines

$a^2=b^2+c^2-2bc\cos A\\a^2=4.1^2+6.7^2-2*4.1*6.7\cos 35^\circ\\a^2=16.6958\\a=\sqrt{16.6958}\\a=4.09\\a \approx 4.1$ cm$

The correct option is D.

steposvetlana [31]

Answer:

$14.88

Step-by-step explanation:

Ria earns 1.2 times more than Peter does

Peter earns $12.40

To solve, you have to multiply the amount peter has by 1.2

12.40(1.2) = 14.88

Therefore, Ria earns $14.88

What is the equation of the graph below?

wlad13 [49]

Answer:

$y=cos(x+\pi )$

Step-by-step explanation:

From the graph, we can see that y = -1 when x = 0.

So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.

1. y = cos(x + pi/2) = cos(0 + pi/2) = 0

2. y = cos(x+2pi) = cos(0+2pi) = 1

3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5

4. y = cos(x+pi) = cos(0+pi) = -1

Therefore, the equation of this graph is y = cos(x+pi) = cos(0+pi) = -1.
