The domain is just the x values.
Domain: -8,4,5,7
The volume of a cone is equal to 1/3•pi•r^2•h. If you want to find the volume of something in terms of pi, you must multiply all other numbers and leave the answer without multiplying the pi in.
In this case, the radius is equivalent to 2mi and the height is equivalent to 7mi. This means….
r^2=4
h=7
Now plug in the numbers into the formula for the volume of a cone.
1/3•4•7•pi
28/3pi
The answer is 28/3 pi.
Givens
Male = 138,053,563
Female = 143,368,343
Total
The total equals 281 421 906
Percents
Male = (138,053,563 / 281 421 906) * 100 = 49.1%
Female = ( 143,368,343/ 281 421 906) * 100 = 50.94%
Rounded
Male = 49
Female = 51
Comment.
To find this %s you could just use the first 3 digits of everything.
Total = 138 + 143 = 281
% male = (138/281) = 49.1
% female = (143/281) * 100 = 50.88
These give you the same answers when rounding.
It is A sure do hope this helps
