Answer: [tex]21 = 2\pi r[/tex]
Step-by-step explanation:
To find the circumference of a circle, you can use [tex]2\pi r[/tex]. You can set this equal to 21 (feet). The equation to solve at this point would be [tex]21=2\pi r[/tex].
Determine the area of the following circle
31.4 sq.in.
78.5 sq.in.
15.7 sq.in.
314 sq.in
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
What is the domain of the function?
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
find the points
that go in
between (-4,7)
and (6,5)

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
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 = 15Step-by-step explanation:
Equation of circle:
(x - h) + (y - k) = r², where (h, k) is the center and r is the radiusWe have:
h = 0, k = -16, r = √15Substitute 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 = 15Correct choice is C
7x - 2(3x - 5) = 26
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
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 =
Length x Width x Height =
24x12x15.5 = 4464in^3
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
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

What is the slope-intercept equation for this
standard form equation?
6x - 3y = 12
Step-by-step explanation:
solve for y
subtract 6x from both sides
6x-6x-3y=12-6x
-3y=12-6x
divide both sides by -3
-3/-3y=(12-6x)/-3
y=2x-4
y=mx+b
m=slope
b=y-intercept
2=slope
-4=y-intercept

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.

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
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.
