Answer:
Step-by-step explanation:
Cone
Givens
r = 1.5 inches
h = 4 inches
Formula
V = 1/3 pi r^2 h
V = 1/3 3.14 * 1.5^2 * 4
V = 1/3* 3.14 * 2.25 * 4
V = 9.42
Semi sphere
Givens
r = 1.5
Formula
V = 2/3 * pi * r^3
Solution
V = 2/3 * 3.14 * 1.^3
V = 7.065
Total
V = 9.42 + 7.065
V = 16.485
Rounded to the nearest 1/100
V = 16.49

Answer: Lattice parameter, a = (4R)/(√3)
Step-by-step explanation:
The typical arrangement of atoms in a unit cell of BCC is shown in the first attachment.
The second attachment shows how to obtain the value of the diagonal of the base of the unit cell.
If the diagonal of the base of the unit cell = x
(a^2) + (a^2) = (x^2)
x = a(√2)
Then, diagonal across the unit cell (a cube) makes a right angled triangle with one side of the unit cell & the diagonal on the base of the unit cell.
Let the diagonal across the cube be y
Pythagoras theorem,
(a^2) + ((a(√2))^2) = (y^2)
(a^2) + 2(a^2) = (y^2) = 3(a^2)
y = a√3
But the diagonal through the cube = 4R (evident from the image in the first attachment)
y = 4R = a√3
a = (4R)/(√3)

x= -4 because 1.4 times -4=- 5.6 and 2.6 times -4=-10.4 and when we add to numbers postive or negative numbers it stays positive or negative depnding on the problem and 10.4 + 5.6 + 16 however becuase both were negative the answers stays negative making the answer _ 16 and it says 1.4x+2.6x=-16 so the correct answer is x= -4
