Answer: 158.26cm³
Step-by-step explanation:
First, we.need to calculate the volume of the cylinder and this will be:
Volume = πr²h
Volume = 3.14 × 3² × 8
Volume = 3.14 × 9 × 8
Volume = 226.08cm³
Since the jar is 70% full, the volume will be:
= 70% × 226.08cm³
= 0.7 × 226.08cm³
= 158.26cm³
Note:
Radius = Diameter/2 = 6cm/2 = 3cm
f(x) = (x - 2)3 + 2x
Answer:
5x-6

Answer:
6 bags with 4 pencils and 6 stickers each.
I need help with finding the volume of this rectangle and also what formula you used so I can understand it. Thanks
Answer:
Step-by-step explanation:
Equation
The volume formula is
V = L * W * H
Givens
From the diagram
L = 6 mi
W = 2 mi
H = 5 mi
Solution
V = 6 * 5 * 2
V = 60 cubic miles

parallelogram. Draw the parallelogram.
Part B
What is the length of side JK? How do you know?
Answer:
[tex]k =(2,1)[/tex]
[tex]JK = 2[/tex]
Step-by-step explanation:
Given
[tex]J = (0,1)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]H = (1,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]I = (3,-2)[/tex] --- [tex](x_3,y_3)[/tex]
See attachment for grid
Solving (a): The coordinates of K
The parallelogram has the following diagonals: IJ and HK
Diagonals bisect one another. So:
Midpoint of IJ = Midpoint of HK
This gives:
[tex]\frac{1}{2}(I + J) = \frac{1}{2}(H+K)[/tex]
[tex]\frac{1}{2}(x_3+x_1,y_3+y_1) = \frac{1}{2}(x_2+x,y_2+y)[/tex]
[tex]\frac{1}{2}(3+0,-2+1) = \frac{1}{2}(1+x,-2+y)[/tex]
[tex]\frac{1}{2}(3,-1) = \frac{1}{2}(1+x,-2+y)[/tex]
Multiply through by 2
[tex](3,-1) = (1+x,-2+y)[/tex]
By comparison:
[tex]1 + x = 3[/tex]
[tex]-2 + y = -1[/tex]
Solve for x and y
[tex]x = 3 - 1 =2[/tex]
[tex]y = -1 +2 = 1[/tex]
So, the coordinates of k is:
[tex]k =(2,1)[/tex]
The length of JK is calculated using distance (d) formula
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
[tex]J = (0,1)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]k =(2,1)[/tex] ---- [tex](x_2,y_2)[/tex]
So:
[tex]d = \sqrt{(0 - 2)^2 + (1 - 1)^2[/tex]
[tex]d = \sqrt{(- 2)^2 + (0)^2[/tex]
[tex]d = \sqrt{4 + 0[/tex]
[tex]d = \sqrt{4[/tex]
[tex]d = 2[/tex]
Hence:
[tex]JK = 2[/tex]

Answer:
Seperate the shapes!
Step-by-step explanation:
CIRCLE
First we want to find the area of the circle which would be:
\pi r^{2}
3.14159265359 x 2^{2}
3.14159265359 x 4cm
= 12.5663706144cm^{2} /2 (must divide by two because it is half of a circle)
= 6.28318530718cm^{2}
RECTANGLE/SQUARE
Find the area of the square.
AREA = L x W
Length = 2cm + ?
Width = 6cm
To find the length we must use the diameter of the circle (which is the radius but times it by 2)
To find diameter: r x 2
= 2cm x 2
= 4cm
Length = 4 + 2 = 6cm
Width = 6 cm
Area (Length x Width) = 6cm x 6cm
= 36cm^{2}
TOTAL AREA:
Just add the area of the circle and the area of the square together.
Area total = 36cm^{2} + 6.28318530718cm^{2}
= 42.2831853072cm^{2}
* Also round your total answer to the nearest tenth or hundreth if needed to do so.

Hanako is putting up a fence around their rectangular yard. The fence will be 15 yards long and 6 yards wide. What is the area of Hanako's fence, in square yards?
Answer:
90 Square Yards
Step-by-step explanation:
To find the area of a rectangle, all you do is multiply the length by the width.
in your equation, the length is 15 and the width is 6.
And 15 x 6 = 90, so the answer is 90 Square Yards.

How can you tell when a variable is a
perfect square?
Answer:
hope this helps
Step-by-step explanation:
If a variable with an exponent has an even exponent then it is a perfect square. To get the square root, we simply divide the exponent by 2. For example x8 is a perfect square, its square root is x4

6+1, 6+2, 6+3, 6+4, 6+5, 6+6
number of even sums within combos:
1+1, 1+3, 1+5
2+2, 2+4, 2+6
3+1, 3+3, 3+5
4+2, 4+4, 4+6
5+1, 5+3, 5+5
