Answer:
These are the properties of a parallelogram
• Opposite angles are equal
• The sum of all the angles is equal to 360 degrees
• Opposite angles are equal
• When the diagonals of a parallelogram are drawn, they bisect each other
• When a diagonal is drawn to separate the parallelogram into two, the two separate sides are equal when compared
• The sum of two adjacent angles in parallelogram is equal to 180 degrees
Step-by-step explanation:
For example,
Opposite angles (A and D) and (B and C) are equal
The sum of all the angles give 360 degrees, angles A + B + C + D = 360
Side AB is equal to side CD (/AB/ = /CD/)
The sum of adjacent angles A and C gives 180 [angles (A + C ) = 180]

❖ Mean = 4.8 Median = 4.5
The mean is the average. To find the mean add up all the numbers and divide by the number of numbers:
3 + 3 + 4 + 5 + 5 + 9 = 29
29 ÷ 6 = 4.8
To find the mean, keep crossing out numbers until you are left with one number (for an odd amount of numbers). When you have an even amount of numbers, keep crossing out until you are left with 2 numbers. Add those 2 numbers and then divide:
4 + 5 = 9
9 ÷ 2 = 4.5

Step-by-step explanation:r
Answer:
3 cm
Step-by-step explanation:
So the area of the total circle is:

If you remove the outer band you have the area of the inner circle

This means that the inner circle had an area of
area = pi * r^2
9 pi = pi * r^2
r =

So the radius of the inner circle is 3.
Answer:
Step-by-step explanation:
area=πr^2
so we need to find the area then divide by 8
so
we know that diameter=2radius or diameter/2=radius so
12=diameter
12/2=radius=6
subsitute
area=π(6)^2
area=36π
divide 36π by 8
36π/8=18π/4=9π/2π=4.5π
area of one section is 4.5π square feet or if we aprox pito 3.14159 then we get
4.5(3.14159)=area=14.1372 square feet or 14.14 square feet
