Answer choices for A : 6, 5 , 5.5
Vsevolod [243]

Answer:

A = 6

B = 29

C = 29

D = 151

Step-by-step explanation:

From the given figure,we get <3 = <5 ( corresponding angle)

A)

<u>if <3 = 5x - 1 and <5 = 3x + 11 then x =?</u>

<3 = <5

5x - 1 = 3x + 11

5x - 3x = 11 + 1

2x = 12

x =6

B)

<u>if <3 = 5x - 1 and <5 = 3x + 11 then  <3 = ?</u>

x = 6

<3 = 5x - 1= 5*6 - 1 = 30 - 1= 29

<3 = 29

<u>if <3 = 5x - 1 and <5 = 3x + 11 then  <1= ?</u>

x = 6

<1 = <3 = 5x -1

<1 = 5*6 - 1 = 29

<1 = 29

<u>if <3 = 5x - 1 and <5 = 3x + 11 then  <2 = ?</u>

x = 6

<2 = 180 - <3

<3 = 29

<2= 180 - 29 = 151

<2 = 151

What is the approximate volume of the cylinder? Use 3.14 for π. Cylinder with height of 22 centimeters and radius of 9 centimete
mamaluj [8]

The volume of a cylinder is found through the following formula:


V = \pi r^2 h


We already have all of our values needed for this formula, so plug them into the equation:


\pi = 3.14

r = 9

h = 22


V = (3.14)(9)^2(22)

9^2 = 9 \times 9 = 81

3.14 \times 81 \times 22 = \boxed{5595.48}


Rounded to the nearest ones value, the approximate volume of the cylinder will be 5595 cubic centimeters.
