Answer:
4188.8 cm^3
Step-by-step explanation:
We can calculate the volume of a sphere by using the following equation:

(r=radius)
so let's just plug in what we know
4/3(pi)(10)^3
we can calculate this with a calculator to get 4188.8 cm^3.
Answer:
Option A: 12
Step-by-step explanation:
From the image of the triangle given, we can see that:
XM = ZM
We are given that:
XM = 2x + 2 and ZM = 4x - 8
Thus;
2x + 2 = 4x - 8
Rearrange to get;
4x - 2x = 8 + 2
2x = 10
x = 10/2
x = 5
Thus, XM = 2(5) + 2
XM = 12
