Answer:
14.14 cm
Step-by-step explanation:
The formula for the area of a circle is : [tex]\pi *radius^2[/tex]
In order to find the radius you would first have to divide the area of 628 by pi, this gives you 200. This is because by dividing the area by pi it will leave us with the radius squared.
The next step is to find the square root of 200, this gives us 14.14. This is because by finding the square root it will leave us with the radius. The square root is another number that when multiplied by itself equals the number.
1) Divide 628 by pi.
[tex]628/\pi =200[/tex]
2) Find the square root of 200.
[tex]\sqrt{200}=14.14[/tex]
Pi as in 3.14

Answer: You find it by using slope
Step-by-step explanation
If the graph is rising from left to right, like climbing a hill, the slope is positive (on a graph, you could count up y units divided by right x units). If it is going down from left to right (like sliding down a hill), the slope is negative (on a graph you have to count down y units and right x units).
ex: y = 5x + 3 is an example of the Slope Intercept Form and represents the equation of a line with a slope of 5 and and a y-intercept of 3. y = −2x + 6 represents the equation of a line with a slope of −2 and and a y-intercept of 6.

Answer:
74
Step-by-step explanation:
Both angles x and 106 are supplementary which means
x+106=180
x=180-106
x=74
Answer:
74°
Step-by-step explanation:
In the image you have provided, angle 'x' and 106° are co-interior angles. This mean that both the angles add up to 180°. We can easily identify co-interior angles because the angles would be inside. The other types of angles you can get is vertical and corresponding. Using the information in the second sentence we can set up an equation,
⇒ Form an equation
→ x + 106 = 180
⇒ Minus 106 from both sides to isolate x
→ x = 74°
The values of angle x is 74°

Kyleigh put a large rectangular sticker on her notebook.the height of the sticker measures 10 cm. the base is half as long as the height. what area of the notebook does the sticker cover?
Hey there! Welcome to Brainly! I'm happy to help you!
When we are talking about the height and base, let's use the variables h and b. With the information we have been given, we can make the following equations below.
h=10 (the height is 10)
b=h/2 (base is half as long as the height)
We see that h is equal to ten. b is equal to h divided by two, so it is therefore ten divided by 2! We take the value for h and the plug it into the second equation!
b=10/2
b=5
So, we now know that the height is 10 cm and that the base is 5 cm. However, we need to find the area. To find the area of a rectangle, we just multiply the base by the height!
10(5)=50
Therefore, the area of the sticker is 50 cm².
I hope that this helps! Have a wonderful day!

The value of the equation is 1.
The equation given is (x-1)/(x-1) = 1.
To determine the solution, we can simplify the equation by canceling out the common factor (x-1) on both sides:
(x - 1)/(x - 1) = 1
1 = 1
The simplified equation 1 = 1 is always true for any value of x.
Therefore, the original equation is true for all values of x, except when x = 1.
When x = 1, the equation is undefined because the denominator becomes zero, resulting in division by zero.
Hence the value of the equation is 1.

To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches. How many cubic inches of frosting is in the bag? Use 3.14 for pi.
Answer:27.7
Step-by-step explanation:
the formula for a cone is V=1/3πr*2h
it is 1/3 because a cone is one-third of a sphere.
you then put the information from the text in the formula and you get this
V=1/3x 3.14 (pi) x 2.1 to the power of 2 (radius is half of a diameter)x 6 (height)
then you get the answer 27.6948
round to the nearest 10th and you get
A. 27.7
Also, I took the test.
There are 27.77 in³ of frosting is in the bag.
What is volume?The amount of space, measured in cubic units, that an object or substance occupies.
Given that, To apply frosting to a cake, a baker twists a plastic bag containing the frosting into a cone shape with a diameter of 4.2 inches and a length of 6 inches.
Volume of cone = ¹/₃πr²h
r = 4.2/2 = 2.1 in
h = 6 in
Volume = ¹/₃x2.1x2.1x6
= 27.77
Hence, the volume of the cone is 27.77 in³

Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
(4)
Here b = 25 and h = 17, thus
A = 0.5 × 25 × 17 = 212.5 cm²

Here b = 12 and h = 20, thus
A = 0.5 × 12 × 20 = 6 × 20 = 120 in²

Find the constant of proportionality (r) in the equation: y = rx
r = ?
Thanks :)
Answer:
r = 11
Step-by-step explanation:
Given
The above table
y = rx
Required.
Find the constant of proportionality.
To find the constant of proportionality, we simply test the values of y and x in the given formula.
Using y = rx
Make r the subject of formula by dividing both sides by x
y/x = rx/x
y/x = r
r = y/x
From the above table of data;
When x = 2, y = 22
So, r = 22/2
r = 11
When x = 7, y = 77
So, r = 77/7
r = 11
When x = 9, y = 99
So, r = 99/9
r = 11
Notice that r maintains the value of 11 all through.
Hence, the constant of proportionality, r for the above data is 11
Answer:
r = 11

The sphere is stacked on top of a cone. They both share a circular base. The radius of the circle is 6 millimeters. The height of the cone is 14 millimeters. The volume of the composite figure is to determine.
Volume is defined as the ratio of the mass of an object to its density.
Volume of composite figure = Volume of semi-sphere + Volume of cone
= 2/3πr³ + 1/3πr²h
= 2/3*6³π + 1/3*6²*14π
