Answer:
9
Step-by-step explanation:
You have to read your givens carefully and then get rid of the information you don't need.
The key fact is that CM = 3
The centroid divides the median into a one to two ratio. So
1/2 = CM/DM where D is apex of the triangle. It is where two of the sides meet, plus the median going to C.
1/2 = 3/DM Cross multiply
DM = 2 * 3
DM = 6
Therefore the length of the median going to C is DM + CM = 6 +3 =9
Brandon is 25 and Keven is 18.
To find this answer, you must first subtract 7 from 43. This will give you 36. By doing this, you're taking away that 7 year difference temporarily.
Next, divide 36 by 2, since there are 2 people. This gives you 18, which is how old Keven is.
Lastly, add 7 to 18, giving you 25. Thus meaning Brandon is 25.
I hope this helps!
The surface area of a sphere is...
A = 4 pi r^2
We would find the radius in which we make this an equation of the radius.
r = (sqrt A pi) / 2 pi
Once we identify r we would then input the radius in the equation for the volume of a sphere....
<span>V = 4/3 pi r^3</span>
