What is the area of the shaded region

Answer:

  18.8 m²

Step-by-step explanation:

The area of a sector is given by the formula ...

  A = (1/2)r²θ . . . . . . . r is radius, θ is the central angle in radians

To convert an angle in degrees to one in radians, multiply by π/180°.

Your 135° sector has an area of ...

  A = (1/2)(4 m)²(135°)(π/180°) = 6π m²

  A ≈ 18.8 m²

Answer: 1/36

Explanation: In this problem, we're given that a number cube is rolled twice and we're asked to find the probability of rolling a 4 and a 4.

It's important to understand that the two rolls of the number cube are independent events because the results of one role does not affect the results of the other roll.

To find the probability of two independent events, we first find the probability of each event, then we multiply the probabilities.

So let's first find the probability of rolling

a 4 with our first role of the number cube.

We can find the probability of an event using the following ratio:

number of favorable outcomes over total number of outcomes

Since there's only one way to roll a 4 and there are six possible outcomes 1, 2, 3, 4, 5, and 6, the probability of rolling a 4 is 1/6.

Next, we find the probability of rolling a 4 with our second roll of the number cube, which would also be 1/6.

Now, to find the probability of rolling a 4 and a 4,

we simply multiply the probabilities.

Now multiply 1/6 x 1/6 by multiplying across the top and bottom.

This gives us 1/36.

So the probability or likelihood of rolling a 4 two times in a row is 1/36.

Answer:

for 9, the answer is 246.49

Step-by-step explanation:

This is area of a circle correct?

The formula is PI x radius squared.

3.14 x the radius, which is 5, squared

I am re-editing this

so sorry the answer is actually 78.54

The reason why it is 78.54 is that you need to square the radius before multiplying with PI.

Step-by-step explanation:

okay, so the area of a circle can be found with the formula πr^2

this means you have to square the radius of the circle and multiply it by pi to find your answer.

9) r=5

πr^2

π(5)^2 = 25π or about 78.54cm^2

this is how you get the area of all other circles!

10) r=9

πr^2

π(9)^2 = 81π or about 254.47mi^2

11) r=8

πr^2

π(8)^2 = 64π or about 201.06mi^2

12) r=4.5

πr^2

π(4.5)^2 = 20.25π or about 63.62in^2

13) r=6.6

πr^2

π(6.6)^2 = 43.56π or about 136.85yd^2

14) r=2

πr^2

π(2)^2 = 4π or about 12.56cm^2

15) r=9

πr^2

π(9)^2 = 81π or about 254.47in^2

16) r=7

πr^2

π(7)^2 = 49π or about 153.94km^2

Answer:

y = -x-2

Step-by-step explanation:

We are given a slope of -1 and the y intercept of -2

The slope intercept form of the equation for a line is

y = mx+b

where m is the slope and b is the y intercept

y = -1x +-2

y = -x-2

Answer:

y=-x -2

Step-by-step explanation:

Slope-intercept form is

y=mx+b

where m is the slope and b is the y-intercept

We know that the slope is -1. We also know that the y-intercept is (0, -2). For this form, we can disregard the 0, and say the y intercept is just -2.

So, m is -1, and b is -2. Substitute the values into the equation.

y=mx+b

y=-1x+-2

Simplify

y= -x -2

This is the equation of the line in slope-intercept form.

Answer:

1/4

Step-by-step explanation:

The slope is given by

m = (y2-y1)/(x2-x1)

    = (-5- -4)/(-6 - -2)

    = (-5+4)/(-6+2)

    = (-1) / -4

Answer:

Sharing cone holds 9 times more popcorn than a skinny cone.

Step-by-step explanation:

Height of each cone = 9 inches

Radius of the sharing size cone = 3 times radius of the skinny size cone

Let the radius of skinny size cone = r

Then radius of the sharing size cone = 3r

Volume of the sharing size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]

                                                     = [tex]\frac{1}{3}(\pi )(3r)^{2}(9)[/tex]

                                                     = 27πr²

Volume of the skinny size cone = [tex]\frac{1}{3}(\pi )(\text{Radius})^{2}(\text{Height})[/tex]

                                                       = [tex]\frac{1}{3}(\pi )(r)^{2}(9)[/tex]

                                                       = 3πr²

Ratio of the volumes = [tex]\frac{\text{Volume of sharing size cone}}{\text{Volume of skinny size cone}}[/tex]

                                   = [tex]\frac{27\pi r^{2}}{3\pi r^{2} }[/tex]

                                   = 9

Therefore, sharing cone holds 9 times more popcorn than a skinny cone.

Answer:

The radius of the water bottle is 2.25 cm

Step-by-step explanation:

The water bottle is said to be cylindrical, so its volume can be expressed as the volume of a cylinder.

Volume of a cylinder V = πr^2 h

Where;

h = height

r = radius

Making the radius the subject of formula;

r^2 = V/πh

r = √(V/πh)

Given:

Volume V = 121 cm^3

height h = 7.6 cm

π = 3.14

Substituting the given values;

r = √(121/(3.14×7.6))

r = 2.25 cm

The radius of the water bottle is 2.25 cm

Step-by-step explanation:

find the area under the graph. i have split it into 3 areas A, B and C

A (trapezium) = 1/2 x (150 + 160) x 15 = 2325

B (trapezium) = 1/2 x (15 + 6 ) x (160 - 110) = 525

C (triangle) = 1/2 x 10 x 6 = 30

total = 2325 + 525 + 30 = 2880

Answer:

Probably Dog.

Step-by-step explanation:

Since there is more dogs than anything else, it would probably be a dog.

Answer:

Total pets  available

20 pets

Cat  0.2 --> 20%

Dog  0. 35  --> 35%

Snake   0.05 --> 5%

Rabbit  0.15 --> 15%

Bird 0.25--> 25%

Step-by-step explanation:

Total pets are:

cats + dogs + snakes + rabbits + birds

4 + 7 + 1 + 3 + 5 = 20 pets available for adoption

To find probability dived the number available of each  pet by the total number of pets available.

Cat

4/20 = 0.2 --> 20%

Dog

7/20 = 0. 35  --> 35%

Snake

1/20 =  0.05 --> 5%

Rabbit

Answer: B and E

Step-by-step explanation:

x√11 and -6√11 are the like radicals of √11.

Radicals are expressions which includes root of any degrees like square root, cube root or generally any nth root.

Usually radical denotes the square root and cube root.

There are three different components for the radical namely radicand, symbol and degree.

Like radicals are radicals whose degree and radicands are the same. Radicand is the number inside the root and the degree of the root is the times that radicand is multiplied to itself.

So these two components must be the same for two radicals to be like radicals.

This does not depend on whatever coefficients the radicals have.

Here, x√11 and -6√11 are the like radicals of √11.

Hence, by the definition of like radicals, x√11 and -6√11 are the like radicals of √11.

The length of AP is calculated by:

L = sqrt((3 - -4)^2 + (-4 - 1)^2) = 8.60

THe length of ZP is calculated by:
