There isnt a number its represented by a variable. So the answer would be n/4-10=2
Answer:
7
Step-by-step explanation:
19 - 4(3) = 19 - 12 = 7
please give me a brainiest
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>
