We have that the formula of the volume of a Sphere is
a.
the radius of the sphere is r=2
the volume will be
b.
the radius of the sphere is r=4
the volume will be
c. as we can see the radius of the sphere b, is twice the radius of sphere a, but as we can see because we calculated the volume of spheres, the volume of the sphere b is much bigger than the twice of the volume of the sphere a. It is because we don't have a linear relationship because we have an exponent 3 in the radius in the formula of the volume
The horizontal axis of the graph represents time, from 65,000 BCE (Before Current Era) to the present. Periods of 5,000 years are separated by vertical lines.
The vertical axis shows the total size of the world population, which has grown spectacularly over the period. Between 50,000 BCE and the present day, the number of human beings has risen from around 600,000 to 6.5 billion, a ten thousand-fold increase.
If that helps :)
Answer:
Step-by-step explanation:
7/15 + 3/5
I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.
Now all we have to do is add the Numerators tog
7/15 + 9/15ether (the top number)
7/15 +9/15 = 16/15 or 1 1/15
