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:
x=−2±3i√2
Step-by-step explanation:
Use the formula ( b/2 )^2 in order to create a new term. Solve for x by using this term to complete the square.

is a multiple of. We know that
is a multiple of
, because
*3=

We can divide fractions to determine if
is a multiple of
:
;
in order to divide fractions, flip the second one and multiply:
)*
=
=1
.
This did not divide evenly, so
is not a multiple of 1/2.
Checking to see if
is a multiple of
,
;
flip the second one and multiply:
*
=
=6.
This divided evenly, so
is a multiple of
.
If you would like to solve blank of 100 equals 16%, you can calculate this using the following steps:
x of 100 equals 16%
x * 100 = 16%
x * 100 = 16/100 /100
x = 16/100 / 100
x = 0.0016
The correct result would be: 0.0016 of 100 equals 16%.
