Answer:
Option D. {–7, 7}
Step-by-step explanation:
3n^2 = 147
First, divide both side 3
n^2 = 147/3
n^2 = 49
Next, rearrange the variables to one side of the equation as shown below:
n^2 — 49 = 0
n^2 — 7^2 = 0
The above is now difference of two squares. This can be solve by doing the following:
(n — 7)(n + 7) = 0
n — 7 = 0 or n + 7 = 0
n = 7 or n = —7
Answer:
The volume of a sphere of radius r is:
S = (4/3)*pi*r^3
The volume of a cylinder of radius r and height h is:
C = pi*r^2*h
For this problem the height of the cylinders will be equal to the diameter of the spheres, which is equal to two times the radius.
First, let's use the radius: r = 2.
The volume of the sphere will be:
S = (4/3)*3.14*(2)^3 = 33.49
The volume of the cylinder, where h = 2*2 = 4, is:
C = 3.14*(2^2)*4 = 50.24
Now, let's choose the radius r = 3.
The volume of the sphere will be:
S = (4/3)*3.14*3^3 = 113.04
The volume of a cylinder with this radius and h = 3*2 = 6, is:
C = 3.14*(3^2)*6 = 169.56
