Add together your portions 1 + 3 + 5 = 9
divide 72 by 9 = 8
Each portion is multiplied by 8
1 x 8 = 8
3 x 8 = 24
5 x 8 = 40
Your portions are 8kg:24kg:40kg
Is this correct? Add 8 + 24 + 40. Do they equal 72? yes. Your portions are correct.
Answer:
8. -6

Step-by-step explanation:
The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.
2πr = 22π
divide both sides by 2
πr = 11π
divide both sides by π
you get r = 11
So your radius is 11.
To find the area, you must do πr^2 ("^2" means squared)
if you substitute 11 for r you get
11π^2
you can do 11 squared first
11^2 = 121
the area of the circle = 121π
Keep in mind that they said to use 3.14 for π
so you can do 121 x 3.14
Final Answer: 379.94
Hello,
Let l represent length
w represent width
P represent perimeter
P=2(l+w)
22=2(l+w)
Divide 2 from both side
22/2=2(l+w)/2
11=l+w
l=2w+2
Apply this into the first equation
2w+2+w=11
3w+2=11
Subtract 2 from both side
3w+2-2=11-2
3w=9
Divided 3 from both side
3w/3=9/3
w=3 meters
l=2w+2
l=2(3)+2
l=8 meters
If you want to find the area
A=l×w
A=8×3
A=24 square meters. As a result, the length of this rectangle is 8 meters, width is 3 meters, and area is 24 square meters. Hope it help!
