Answer:

The ratio of the volume of cylinder a to the volume of cylinder b is 1 : 2 .

Step-by-step explanation:

We know that,

The volume of a cylinder is,

V=\pi (r)^2 h

Where, r is the radius of the cylinder,

h is the height of the cylinder,

Given,

For cylinder a,

r = 1 m and h = 4 m

Thus, the volume of the cylinder a is,

V_1=\pi (1)^2(4)

=4\pi \text{ square m}

Now, for cylinder b,

r = 1 m and h = 8 m

Thus, the volume of the cylinder b is,

V_2=\pi (1)^2(8)

=8\pi \text{ square m}

Hence, the ratio of the volume of cylinder a to the volume of cylinder b is,

\frac{V_1}{V_2}=\frac{4\pi }{8\pi }=\frac{1}{2}

Answer:yes

Step-by-step explanation: the answer does represent a function because if you were to put points in the line wherever, and connect them by drawing a line vertically, it would not cross two points.

My little sister needs help in this and I don't remember. ​

You have to have the same denominator for both fractions, so I would multiply 3/4 by 3 that would give you 9/12 and the other one is 7/12. This means that the final answer would be 9/12>7/12.

Describe how you know whether an equation will be true for all values of x or true for no values of x
love history [14]

Answer:

<h2>brainiest me</h2>

Step-by-step explanation:

The value returned is TRUE if all of the values in x are TRUE (including if there are no values), and FALSE if at least one of the values in x is FALSE. Otherwise the value is NA (which can only occur if na.rm = FALSE and ... contains no FALSE values and at least one NA value).
