Answer:
The set of solution is {-6,6}
Step-by-step explanation:
That means 2x^2-72=0?
If yes, here the solution for this:
x^2-36=0 (divise both sides by 2)
x^2=36
x^2=6^2
We have x=6 or x= - 6
The set of solution is {-6,6}.

Answer:
The volume of the sphere is 32 π /3 cm^3
Step-by-step explanation:
Mathematically, the volume of a sphere can be calculated using the formula below;
V = 4/3 * pi * r^3
Now since we have the radius and diameter = 2 * radius
radius = diameter/2 = 4/2 = 2
Substituting this value into the volume equation;
V = 4/3 * pi * 2^3 = 32pi/3
