Answer:
216
Step-by-step explanation:
Given the figure.
And the perimeter in the ratio 4: 2: 1.
Perimeter of smallest circle = 
To find:
Area of shaded region.
Solution:
To find the area, we need to have radius first.
And radius can be calculated by the given perimeter.
Formula for Perimeter is given as:
Perimeter = 

Radius of smallest circle = 4 cm
Ratio of perimeter is equal to the ratio of the radii.
Radius of 2nd smallest circle by the given ratio = 8 cm
Radius of largest circle = 16 cm
Area of a circle is given the formula:

Area of the smallest circle = 
Area of the 2nd smallest circle = 
Area of the largest circle = 
Area of the shaded region = Area of largest circle + 2
Area of 2nd smallest circle + 3
Area of smallest circle - 2
Area of smallest circle - 3
Area of 2nd smallest circle
Area of the shaded region = Area of largest circle - Area of 2nd smallest circle + Area of smallest circle = 
Answer:
lets make it an improper fraction:
17/6 x 8/1(consider 8 over 1) = 22 2/3
Simplify first though
17 x 8 divide by 2 = 4
_____
6 divide by 2 = 3 (8 and 6 are divisible by 2)
Your new simplified multiplication:
17 x 4
_____ then you can do your multiplication across.

22.5/5 = 4.5
For every 4.5 minute, she runs 5 km
12 different combinations because 4 times 3 equals 12.
B because oil has a lower density than water so oil is on top while water has a higher density and goes down
