Answer:
I had it before and it is 15 ft²
Answer:
Step-by-step explanation:
The distance (d) between two points in 3 dimensions is ...
d = √((x2 -x1)² +(y2 -y1)² +(z2 -z1)²)
Then the distance between (a, -b, -4) and (0, 0, 0) is ...
d = √((a -0)² +(-b -0)² +(-4 -0)²)
= √(a² +b² +16)
The volume formula for a cylinder is :
V= (pi)(r^2)(h)
So r= d/2 where d = 16mm so r= 8mm h is given as equaling 5.7mm
Now just plug it into the formula.
V=(pi)(8^2)(5.7) = 364.8 pi mm = 1146.053mm
At its neutral state, an element has equal number of protons and electrons. If not, they occur as ions. The most stable elements are the noble gases. The nearest noble gas to Lithium is Neon, which is one proton lower than Lithium. Hence, when Lithium has a charge, it is naturally +1 because it has to give one electron to be as stable as Neon.
