The radius of a cylindrical construction pipe is 2 ft. If the pipe is 17 ft long, what is its volume?
Use the value 3.14 for it, and round your answer to the nearest whole number.

Answers

Answer:

[tex]volume \: = \: \pi \times r {}^{2} \times length(height) \\ = 3.14 \times 2f \times 17ft \\ = 106.76ft {}^{3} [/tex]

Answer:

V = 106.76ft

Step-by-step explanation:

Cylinder Formulas in terms of r and h

Calculate the volume of a cylinder: V = πr2h

Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2πrh

Calculate the top and bottom surface area of a cylinder (2 circles): T = B = πr2

Total surface area of a closed cylinder is: A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)

a² + b² = c²

9² + 12² = x²

The length of the side AC will be equal to 5.69 cm

What is quadrilateral?

A figure consisting of four sides connected together and forming a total angle of 360 degrees is called a quadrilateral.

Given that:-

ABCD is a kite, so AC I DB and DE= EB.

AD = 4 cm BD = 4 cm and CD = 3 cm.

The side AC will be calculated as:-

Since AC is bisecting the line BD so BE = ED and BE = 2 cm and ED = 2 cm. WE have AD = 4 cm so we will calculate AE first by using the Pythagorean theorem.

AE² = AD² - ED²

AE² = 4² - 2²

AE² = 16 - 4 = 12

AE = √12 = 3.46 cm

Similarly, we will find the value of EC.

EC² = 3 ² - 2²

EC² = 9 - 4 = 5

EC = √5 =2.23

WE know that AC = AE + EC

AC = 3.46 + 2.23

AC = 5.69 cm

Therefore the length of the side AC will be equal to 5.69 cm

Aram has been studying the mathematics behind pinball machines. He made the following diagram of one of his
observations. Determine the measure of the missing angle.

Answers

Given:

A diagram of Aram's observations.

To find:

The measure of the missing angle.

Solution:

From the given figure it is clear that the three angles [tex]52^\circ,x^\circ,68^\circ[/tex] lie on a single point and right side of a straight line.

So, the sum of angle [tex]52^\circ,x^\circ,68^\circ[/tex] must be [tex]180^\circ[/tex].

[tex]52^\circ+x^\circ+68^\circ=180^\circ[/tex]

[tex]x^\circ+120^\circ=180^\circ[/tex]

[tex]x^\circ=180^\circ-120^\circ[/tex]

[tex]x^\circ=60^\circ[/tex]

Therefore, the measure of the missing angle is [tex]x^\circ=60^\circ[/tex].
