What is the volume of the cylinder shown below?

B) 1452π units³

Step-by-step explanation:

To find the Volume of a cylinder, use this formula:

V (cylinder) = πr²h

Note that:

r = radius of the circle (base) = 11

h = height of the cylinder = 12

π = 3.14

Plug in the corresponding numbers to the corresponding variables.

V = (3.14)(11)²(12)

Remember to follow PEMDAS. First, solve for the power, then solve left -> right.

V = (3.14)(121)(12)

V = (379.94)(12)

V = 4559.28 units³

Note that the answer choices have π  in them, divide π from the answer, and add to the answer.

V = (4559.28)/3.14 = 1452π units³

B) 1452π units³ is your answer.

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
