Answer:

169.56 m³

Step-by-step explanation:

» Concepts

The volume of a cylinder is how much space there is inside the cylinder. The formula to find the volume is πr²h, where r = radius and h = height. Once you get the volume, you have to add <unit>³.

» Application

We are given the radius as three meters and the height as six meters; we also have to use π as 3.14. Now, we just have to plug in these values into the aforementioned formula.

» Solution

Answer:

5.236 units

Step-by-step explanation:

The relation between r, θ and arc length ( l ) is,

l = rθ

l = 1 * 5π / 3

( The value of π = 3.14 approximately )

5π = 5 x 3.14 = 15.7

l = 1 * 5π / 3

= 5π / 3

= 15.7/3

l = 5.236 units

Note : -

Arc length is denoted by " l ".

The potential problems is the simulation or method to analysis what is gone wrong in a particular program.

She sets her chess computer program to play 100 first moves in the game of chess. In this simulation, she only focuses on first move and overstimulated the situation.

Antonia concludes that of the 20 possible opening moves in chess, most players will move the pawn piece in front of the queen forward two spaces.

In this conclusion she has misleading data as each player has different strategy.

Thus, the potential problems with Antonia's simulation is that she over simulated the situation and her conclusion has the misleading data.

Answer:

156.32 joules 

Step-by-step explanation:

In this case, we know the force of 64 N and the distance of 3 m. We also know that there is a 120°angle between the angle of the direction of applied force and the direction of motion. So plugging these values into our handy equation yields:

W = 64(3)cos(120)= 156.32 Joules

So the 64 N force at a 120° angle did 156.32 joules of work moving the book 3 meters.

Step-by-step explanation:

This can be modeled as a binomial distribution as:

Let "success" be the balloon popping.

⇒ trials (n) = 3

⇒ probability of success (p) = 0.10

To find the probability that all 3 of the balloons pop, use the binomial distribution with x = 3:

(f - g)(x) = x - 6

Answer:

128 cubes can fit in.

Step-by-step explanation:

We are given: Volume of rectangular prism = 2 units³ and Cube with edge = 1/4 unit

We must find: The number of cubes that can fill the prism

Firstly, find the volume of 1 cube:

Volume = 1/4 x 1/4 x 1/4

Volume = 1/64 units³

Next find the number of cubes that can go into the prism:

Number of cubes = 2 ÷ 1/64

Number of cubes = 128

Therefore 128 cubes can fit in.

Step-by-step explanation:

both the x-intercepts are (4,0)

Answer:

The median of the data set:

6, 15, 30, 45, 47, 49

The middle numbers are 30 and 45 so

You have to do 30 + 45

= 75

Then do 75 ÷ 2

= 37.5

The mean of the data set:

47, 15, 6, 49, 45, 30 (add them all)

= 192

Then divide 192 by 6 (because there are 6 numbers)

192 ÷ 6

= 32

So the median is 37.5 and the mean is 32.

Answer:

x^2 + y^2 = 9

Step-by-step explanation:

The equation of a circle is (x^2) -a)^2 + (x^2) - b)^2 = r^2, where a and b are the center of the circle. Because the center of the circle is (0,0), it'll just be x^2+y^2 for one half of the equation. If the circle passes through (-3,0), that would mean the radius of the circle is 3. r^2 is 3^2, which is 9, so the equation of the circle is x^2 + y^2=9. Hope this helps!

The equation of the circle is x² + y² = 9

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the point be represented as A ( -3 , 0 )

Now , the center of the circle = O ( 0 , 0 )

And , standard form of a circle is

( x - h )² + ( y - k )² = r²

where In this case, we know that the circle passes through the point (-3, 0) and is centered at the origin (0, 0). Therefore, the radius of the circle is the distance from the origin to (-3, 0), which is:

r = √((-3 - 0)² + (0 - 0)²) = √(9)

r = 3 units

So the equation of the circle in standard form is:

(x - 0)² + (y - 0)² = 3²

On simplifying , we get

x² + y² = 9

Hence , the equation in standard form for the circle passing through (-3,0) centered at the origin is x² + y² = 9
