Determine the area of the following circle

31.4 sq.in.

78.5 sq.in.

15.7 sq.in.

314 sq.in​

Answers

Answer:

31.6 sq.in i got by using 2pier formula

Step-by-step explanation:

area of a circle = πr²

where π = pi = 3.14

r = radius = 5in

area= 3.14 (5²)

= 3.14 x25

= 78.5 sq.in

10) A circle has center at (-5, 3) and passes through the point (-1, 3).
a) Give the radius of the circle.

b) Give the equation of the circle described.

Answers

a) radius= 4 units

b) (x+5)^2+(y-3)^2=4^2

The distance between the x values in the center point and a point included in the graph will give you the radius.
The x values are 4 units apart (-5 to -1) so your radius is 4 units

Circle formula:
(x-h)^2+(y-k)^2=r^2
Where (h,k) is the center point and r is the radius

Replace h with -5, k with 3, and r with 4 to get equation listed in answer above

What is the domain of the function?

Answers

Answer: -6 ≤ x < 4

Step-by-step explanation:

Open circles on a graph mean that that point is not included

Filled in circles on a graph mean that that point is included

As a result, the end point (-6, -6) is included while (4, 8) is not

The domain is all possible x-values so the graph can be anywhere from:

-6 ≤ x < 4

Note that there are no possible values for the x-value of 4

7x - 2(3x - 5) = 26 ​

Answers

Answer:

x=16

Step-by-step explanation:

7x−2(3x−5)=26

Use the distributive property to multiply −2 by 3x−5.

7x−6x+10=26

Combine 7x and −6x to get x.

x+10=26

Subtract 10 from both sides.

x=26−10

Subtract 10 from 26 to get 16.

x=16

Graph if needed:

Answer:

x = 16

Step-by-step explanation:

7x - 2(3x - 5) = 26 ​

7x - 6x + 10 = 26

7x - 6x + 10 - 10 = 26 - 10

x = 26 - 10

x = 16

The length of packing a box is 24 in. the width is 1/2 of the length. The height is 3 1/2 inches more than the width. What is the volume of the packing box? HELPPPP

Answers

Answer:

4464in^3

Step-by-step explanation:

Length of Box = 24 in.

Width = 1/2 x Length = 1/2 x 24 = 12in.

Height = 3.5 + Width = 3.5 + 12 = 15.5 in.

Volume of box = Volume of Cube =

Find x and y with ray theorem

Answers

Answer:

x = 12 and y = 9

Step-by-step explanation:

Using the similarity theorem to fid the value of x and y

16/x = 16+6/16.5

16/x = 22/16.5

22x = 16*16.5

22x = 264

x = 264/22

x =12

Similarly

24/x = 24+y/16.5

24/12 = 24+y/16.5

2 = 24+y/16.5

24+y = 2 * 16.5

24+y = 33

y = 33-24

y = 9

Hence x = 12 and y = 9

A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

What is a cylinder?

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.

Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,

Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³

Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

What is the length of side d?


A. 5 centimeters
B. 8 centimeters
C. 12 centimeters
D. 25 centimeters

Answers

Answer: A

Explanation:

Use formula a^2 + b^2 = c^2 but in this case letter “d” will substitute for “b”

Since 13 is hypotenuse, 13 is going to be the letter c

12 is “a” because we don’t know “d”

So it’s 12^2 + d^2 = 13^2

Simplify: 144 + d^2 = 169

Subtract to isolate d^2: d^2 = 25

Take square root from both sides to isolate d: d = 5

Write a fraction on the blank to make the comparison true .Use the fractions form the box .Explain how you choose your number 3/5>3-4

Answers

Answer:

Explained

Step-by-step explanation:

So I'm not sure if you mean by 3/4 or 3-4. But I'm going to assume that its 3-4 because 3/4 is greater than 3/5

3/5 is equal to 0.6 -> you can also find 0.6 by multiplying 3/5 * 2 on both sides which will be 6/10 which is 0.6

and 3-4 is - 1 (which is negative)

since 3/5 is positive and 3-4 is negative. You would know that this is true.

PLZ use the information given to write the equation of the circle.
Center: (0,-16), Radius: √15


A: x2+(y+16)2 = 15−−√

B: (x+16)2+y2=15

C: x2+(y+16)2= 15

D: x2+(y−16)2 = 15

Answers

Answer:

x^2+(y+16)^2=15

Step-by-step explanation:

(x-0)^2+{y-(-16)}^e=(√15)^2

→x^2+(y+16)^2=15

Answer:

C. x² + (y + 16)² = 15

Step-by-step explanation:

Equation of circle:

(x - h) + (y - k) = r², where (h, k) is the center and r is the radius

We have:

h = 0, k = -16, r = √15

Substitute the given into the equation above and get the equation of the given circle:

(x - 0)² + (y - (16))² = (√15)² ⇒x² + (y + 16)² = 15

Correct choice is C

How much larger is the circumference of circle A than the circumference of circle B?

Give your answer to one decimal place.
diameter of circle A is 13 and B is 8

Answers

Answer:

Circumference of Circle A is about 16 units larger than the Circumference of Circle B

Step-by-step explanation:

Formula for Circumference of a circle = πd

Where, d = diameter of circle

Thus:

Circle A diameter = 13

Circle B diameter = 8

Therefore:

Circumference of Circle A = π*13 = 40.8407045 ≈ 41 unit (nearest whole number)

Circumference of Circle B = π*8 = 25.1327412 ≈ 25 unit (nearest whole number)

✔️Difference between circumference of Circle A and Circle B = 41 - 25 = 16

Therefore the Circumference of Circle A is about 16 units larger than the Circumference of Circle B
