The volume of a sphere, V = (4/3)(PI)(R^3)
Let k = (4/3)(PI)
Therefore, V = k (R^3)
Let R’ = new radius = 2R
V’ =k (R’^3)
= k (2R)^3
= 8 k R^3
= 8 V
The volume would be eight time the original volume.
Hey this is very easy to learn! So to express a decimal as a percent all we have to do is multiply it by 100. So multiplying .053 by 100 would just mean moving the decimal point 2 spaces to the right.
So the answer would be 5.3%
I hope this helps!

The answer for the first question is 10%.
Reason: The second number (110) is larger than the first number (100) by 10 it is 10% the first number.
.
The answer for the second question is 25%, also.
Reason: The first number (100) is smaller than the second number (110) by 10 and it is 9.1% of the second number.

Answer:
0.3 per year
Step-by-step explanation:
Number of newborn per year: 200*0.5 = 100
Number of death per year: 200*0.2= 40
So, the difference between birth and death = 100-40 = 60 (people)
and the growth rate during the year is: 60/200 = 0.3
