Which of the following statements are true? Select all that apply.

The radius of a circle is twice its diameter.
The radius of a circle is twice its diameter.
The formula to find area of a circle is A=πr2
To find the diameter of a circle, divide its circumference by π.
The circumference of a circle is greater than its diameter.
To find the diameter of a circle, multiply the radius by 2.
The diameter can be used to find area of a circle.

Answers

Answer:

Step-by-step explanation:

By definition, all radii of a circle are congruent, since all the points on a circle are the same distance from the center, and the radii of a circle have one endpoint on the circle and one at the center. ... The length of the diameter is twice that of the radius. Therefore, all diameters of a circle are congruent, too.

The formula to find area of a circle is A=pi(r)2(if that 2 is an exponent ), To find the diameter of a circle divide its circumference by pi, The circumference of a circle is greater than its diameter, To find the diameter of a circle multiply the radius by 2, and the diameter can be used to find area of a circle. :)

B is the correct answer

Answer:

B; or 8.5

Step-by-step explanation:

Mean is also known for average of the numbers.

To find the mean simply add all the numbers together and divide by the quantity of the numbers given. So first add up "8 + 10 + 6 + 4 + 12 + 6 + 8 + 14" this all equals to 68 and since the total quantity of the numbers given is 8, so divide 68 by 8 which gives the answer as 8.5.

a.8
b.4
c.1
d.16

Answers

The number of revolutions it takes the wheel to travel about 192 inches is 4. Therefore, option B is the correct answer.

What is circumference of a circle?

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.

Given that, the diameter of a bicycle wheel is 16 inches.

We know that, the radius of a circle is diameter/2

Here, radius of bicycle wheel =16/2 =8 inches

As we know, the circumference of a circle is 2πr

Now, circumference of bicycle wheel is

2×3.14×8

= 50.24 feet

The wheel to travel about 192 inches

Number of revolutions =192/50.24

= 3.82

≈ 4

The number of revolutions are 4. Therefore, option B is the correct answer.

[tex]0.4 \div 0.2 = 2 \\✓ = option \: 3[/tex]

Answer:

The model that correctly shows the problem 0.4 divided by 0.2 is option 3.

Step-by-step explanation:

Option 3 has 4 out of 10 rowS shaded in, which you can infer immediately is the correct answer. Since 10 rows represent 1 whole, that means that 4 rows shaded in are 0.4. In option 3, the four rows are split by blue lines and have 2 rows, or 0.2, in each group, so option 3 matches the problem 0.4 divided by 0.2.

Amy is having her birthday party at a skating rink. The rink charges $50 plus $8 per person. If Amy wants to spend at most $200, how many people can she invite? (Hint: make sure you include Amy in the head count.)

18

Step-by-step explanation:

Amy can invite 18 people (including herself). $200-$50=$150. $150÷8=18.75. You can't have 18.75 people so you round it down to 18. Hope this helps!

Answer: 18 people including herself

Step-by-step explanation: Take $200-$50=$150

now divide 150 by 8 which is 18.75 you obviously can't round up so you round down to just 18 and thats your answer. she can have 18 people there including herself

Now, you will look at each chart for 3 x's above the number 4. You have now eliminated the middle two. Next, count how many 3's there are, which is 2. Both have those, so eliminating other choices is a no-go. Now, look at how many 5's you have, which is 2. Look at your charts... again, no choice ca be marked-off. Finally, look at how many 6's there are, which is 3. So, look at your last options and find which one has 3 total x's above the 6. And there you go, D.

To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = 14 2/5 in
Height of triangle = 8.5 in
We know that,
Area of triangle =1/2 *base *height =1/2 *8.5 *14 2/5
=1/2 * 8.5 * 14.4
=1/2 * 122.4
=61.2

we get
The area of the triangular case = 61.2 square inches

Answers

Answer:

You could do negative numbers because no positive number is less than 0, as you know.

So, it would have to be a negative one because they are to the left of zero on a number line, meaning less than. A positive number on a number line is usually to the right of zero, meaning more than.

For instance, x could equal -1 and y could equal -4.

It would be in Quadrant 3.
