The volume of a right cylinder is 155.4 ft. 3 The radius is 3 ft. Determine the height of the cylinder.

BigorU [14]

Answer:

The height is approximately 5.4961507

Step-by-step explanation:

The volume of a right cylinder is $v=$ π · r² · h, where r is the radius and h is the height.

We know the radius and volume. We can figure out the height like so:

$v= pi * r^2 * h\\\\\frac{v}{pi * r^2} = \frac{pi * r^2 * h}{pi * r^2}\\\\\frac{v}{pi * r^2} = h$

Now, we just substitute the known values in for their corresponding variables:

$\frac{155.4}{3.1415927 (approx.) * (3)^2} = h\\\\\frac{155.4}{3.1415927 (approx.) * 9} = h\\\\\frac{155.4}{28.2743339 (approx.)} = h\\\\5.4961507 = h$

The height of the cylinder is approximately 5.4961507

A single die is rolled twice. Find the probability of rolling an even number the first time and a number greater than 3 the seco

IceJOKER [234]

Events

• A: an even number is rolled in the first time

• B: a number greater than 3 is rolled the second time

The probability of rolling an even number is:

$\begin{gathered} P(A)=\frac{\text{ number of favorable outcomes}}{\text{ total possible outcomes}} \\ P(A)=\frac{3}{6} \\ P(A)=\frac{1}{2} \end{gathered}$

The probability of rolling a number greater than 3 is:

$\begin{gathered} P(B)=\frac{\text{ number of favorable outcomes}}{\text{ total possible outcomes}} \\ P(B)=\frac{3}{6} \\ P(B)=\frac{1}{2} \end{gathered}$

Events A and B are independent, then the probability of one happening after the other is:

$\begin{gathered} \text{ P(A and B) = }P(A)\cdot P(B) \\ \text{ Substituting with the values previously found:} \\ \text{ P(A and B) = }\frac{1}{2}\cdot\frac{1}{2} \\ \text{ P(A and B) = }\frac{1}{4} \end{gathered}$

I need help with this any help will be appreciated

Mars2501 [29]

Are you trying to solve for x and y?

y=2x+1; x+2y=17
sub in one variable in the other equation.
x+2(2x+1)=17
x+4x+2=17
5x=15
x=3

now that you have x value, plug into the original equation to find y and check with the other.
y=2(3)+1 = 7
x+2y=17 = 3 + 2(7) = 17 ; 17=17
