For this case we have that by definition, the volume of a cylinder is given in the following way:

V = \pi * r ^ 2 * h

Where:

V: Represents the volume

r: Represents the radius of each of the circular caps of the cylinder

h: Represents the height of the cylinder

IF the diameter is 6, then:r = \frac {6} {2} = 3

Then, according to the given data we have:

r = 3\\h = 9

Substituting:

V = \pi * (3) ^ 2 * 9\\V = \pi * 9 * 9\\V = 81 \pi

So, the volume of the cylinder is81 \pi

Answer:

The volume of the cylinder is 81 \pi cubic units

NeX [460]

Options were not present in the question we are Stating below;

Rashida owns a bike rental company. She charges an initial fee of $10 for each rental and an hourly rate of $4. A customer paid $34 for a bike rental. Which of the equations below could be used to find how many hours, x, the customer rented the bike?

34 = 10 - 4x\\\\34 = 4 + 10x\\\\34 = 10 + 4x\\

Answer:

34 = 10 + 4x

Step-by-step explanation:

Given:

Amount customer paid = $34

Initial fee = $10

Hourly rate = $4

We need to write the equation used to find how many hours, x, the customer rented the bike.

Solution:

Let the number of hours customer rented the bike be 'x'.

Now we can say that;

Amount customer paid is equal to sum of Initial fee plus Hourly rate multiplied by number of hours customer rented the bike.

framing in equation form we get;

34 =10+4x

Hence The equation used to find number of hours customer rented the bike is 34 =10+4x.

Suppose that you flip a coin 40 times and count the number of heads. 1.1. What is the distribution of the number of heads assumi
dangina [55]
Answer: You would get 20 heads and 20 tails.

Explanation: Assuming that the coin is fair which you said it is, then you can also assume that there’s a 1/2 probability of getting heads each time you flip it and tails each time you flip it. So since you flipped it 40 times, you would assume to get heads 20 times and tails 20 times.
